I too found an almost complete quare rash on my leg today. It's actually half of a square looking at it side ways. I woke up fine today; cut a lemon squeezed the juice into my water and tossed the peel then ate a salad with vinegarrette dressing that I forgot to wash out it was probably about two or three months old. I also don't think I washed the lemon that well but would it matter since I didn't put the peel in? Anyways right after taking a few bites if the salad I noticed it tasted funky and tossed it then after one drink of water I ran to the bathroom to puke. My mouth started watering uncontrollably. I keep getting light headed and nauseas then throwing up. Do you think maybe I need to take antibiotics? I have cephalexin in my medicine cabbinet that I two months old?? Please help
Hello,
I cannot confirm anything without examination but it can be frictional lichenoid dermatitis, granuloma annulare or psoriatic patches. Psoriasis is a long-term (chronic) skin problem that causes skin cells to grow too quickly, resulting in thick, white, silvery, or red patches of skin.
I suggest you to get an examination done from a dermatologist and get the diagnosis confirmed as treatment is diagnosis specific.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
