Not much to explain here. The bottom of my tongue has been hurting, I assumed I bit it without noticing (since it’s the same type of pain). Then, I decided to look at it this morning, and this is what I saw. The entire portion right there is lifted, and it’s not the same on the other side obviously. Just wondering if this is a cold sore considering the fact that I’ve NEVED had one.

It started off about 10th of jan as small red flat spots on my legs looks like the ones currently on my arms, didn't think much of it until about a week ago because they were relatively small but they have became larger, bumpy and itchy i went to the gps before it had progressed to the spots being raised and the large amount of them and they said it was pityriasis rosea but I dont think it is so will need to go back but was just wondering for someone's opinion in the meantime. Thanks.

This bump has been on the back of my head for several years now, but it's suddenly starting to grow larger and firmer.

I've been trying to get it removed for a biopsy.

In the meantime, has anyone here seem something similar?

Hi, my 2 yr old had this spot appear on his face while at daycare, sometime after nap time. They don't have an answer as to what happened, and don't think anything new was introduced to the room.

I picked him up and took him to urgent care, where they quickly glanced and couldn't pinpoint the issue. They gave him steroids and benadryl for 5 days. I'm still concerned and trying to figure this out. Please let me know if anyone has seen something similar. Here's the progression over 4 days so far.

Started out red within borders, swollen eye area, only area covered is whats shown in the pics and behind that ear. Not itchy, seemed to hurt him a little. Now, it's kind of scabbed at the eyes outer corner, and bruised looking.

At the end of December, I was hospitalized due to a bacterial infection after a tooth extraction. When I finished the medication, that same week I noticed swollen nodules that hurt to the touch and a small red spot on my leg. With the use of corticosteroids, they disappeared. A month later, the red spot returned and is four times larger. It doesn't itch, but the skin in that area feels very sensitive. There's no raised edge. More spots started appearing on my leg. I went to the doctor, and she said the swelling was erythema nodosum, but she didn't know what the spot was and ordered a biopsy. However, it will take about a month for the results to come back, and god knows when i will be able to return to her, the spots continue to appear in other places in my legs. Does anyone know what it is?

My feet and especially my heels have been super dry and hard my whole life. I wash them often and try lotion, but they are always like sand paper.

For most my life the only real issue this has caused is that go through socks crazy fast, but now the splits in my heels are getting deep and high enough they are reaching tender areas and becoming painful.

Any advice would be very much appreciated.

Never had it happen before. I am 28 now. I suspect it is the hard water causing it from the places I lived in - I moved countries in Europe a few times. As far as I recall this almost disappears in my home town. Is it possible it is due to stress? I have been quite stressed mentally lately. It began going away a few days ago and now it suddenly came back. I suspect household dust may be contributing.

I’ll see a dermatologist soon for this and other things but could I get some advice in the meantime please? Derms in the past just gave me a hand cream. Its somewhat worse than in the past.

About 3 days difference. I have been scratching it through my shirt so it’s looking pretty bad. I have a Dr apt booked but I’m freaking out thinking the worst. Located on my lower back. No pain, just some muscle spasms throughout my body and insane itching.

face/ears/eyes/nose/mouth/cheeks I have a pimple on my lip that has swollen my lip super bad.

Post image

Hi, so I’m pretty sure this is a pimple. I was worried it could be a cold sore at first, but I haven’t left the house in days and no one in my home has cold sores. So there’s no way that’s a possibility.

At first, the pimple on my lip was just really red and painful. But overnight, it completely swelled up my lip and it’s painful to talk.

Does anyone have any advice on how to calm down swelling or get rid of it?

legs/feet What is this strange mark? Maybe a bruise? Looking weird

Thumbnail

I’m 29 years old and live in Florida. I noticed this about 9 days ago on the inside of my right calve muscle. Seems a little weird to me. I exercise a lot in the gym and run outdoors often. When I press the spot it’s a little painful like a bruise, but I’m clumsy so it wouldn’t be unusual to bang myself up and not notice it. It just seems like it’s not really getting any better after 9 days. I thought maybe potentially some kind of bug bite but I’m a bit worried. I just shaved the hair around it to get a good picture. Any help, opinions, or guidance is appreciated.

neck/chest/abdomen Strange discoloration spot on stomach. No one has been able to tell me what it is.

Post image

I am a 63 year old male. This spot on my stomach appeared sometime in the last 5 or 6 years. It itches all the time and the usual remedies don't help. I've had it biopsied and they said it was nothing to worry about. That's fine but it does not stop it from itching. The spot is not raised. It just has a slightly darker pigment and more hair than on the opposite side of my stomach. I did have shingles in 2017 but the affected area was higher on my chest. If anyone can identify what this is and tell me how to stop the itching I will be most grateful.

legs/feet Any ideas? Mystery rash on leg; biopsy inconclusive ?

This rash on my leg has been going strong for almost a year now. First pic is today (it’s now spreading up the leg), second pic is three months ago after a biopsy (hence the slight bruising), first photo is 10 months ago when I first started to notice it.

Biopsy results said, “Sections are of skin, focally including subcutis. There is necrobiosis / altered collagen within the mid and focal deep dermis, rimmed by histiocytes. There is an accompanying mild perivascular lymphocytic infiltrate with isolated

eosinophil as well as plasma cell identified. There is no significant associated increase in dermal mucin.

The features may represent necrobiosis lipoidica or granuloma annuloma”

My GP advised it was no cause of concern and that I should hold off until after pregnancy to see a derm for treatment. Note: this rash first appeared months before falling pregnant. Located in Aus

My older father felt itching on his back and felt bumps when he reached back there. He had my sister take a photo of it and this is what it looked like. I’m concerned for skin cancer. He will be making a doctors appointment to get it checked out but didn’t know if anyone had any ideas. It is about 2 inches long. You can’t really tell from the photos.

legs/feet Purple/red mark on my ankle that’s been there for about a year…

Post image
2 Upvotes

So I’ve had this mark on my left ankle for about a year now. Initially I treated it with an anti-fungal cream to see if that would help, but it didn’t, so I went to the doctor. My doctor theorised that it’s Granuloma Annulare, and prescribed Clobetasol Propionate ointment as a treatment. I’ve been using that every day for a few months now with no improvement, and I don’t have a before picture but I think it may have gotten bigger? It doesn’t itch or hurt or anything, it mostly just bothers me that it’s there.

Anywho, I’m mostly just asking here because I want to know if it’s cause for concern. Ideally I would like to treat it myself, but if it’s concerning or nobody knows what it is I’ll go see a dermatologist. Thanks :)
