Hello, a few years ago I had a microscopic parasite that made my legs itchy so when it happened again I went to my Doctor but he told me there were no holes so it was probably an allergic reaction, he gave me a cream that helped a little but didn't stop it.
I searched the net and someone said it might be due to something in bread so I stopped eating bread, then I stopped cakes and even schnitzel and crumbed fish, this did help but I still had it sometimes.
Finally I searched the net again and found it can be caused by lack or water, I realized I had been drinking a lot more coffee so I cut back the coffee and drank more water and it has stopped, my legs finally don't itch and I can eat bread again.
It is simple to test and it worked for me so I hope it helps you because I do understand how this can drive you crazy.
Hello,
This kind of red rash can be due to contact dermatitis, stasis dermatitis, hypertrophic lichen planus or fungal infection( usually it is itchy). I suggest you to get an evaluation done from a dermatologist. Till then keep your leg elevated while sitting and apply some calamine lotion of the rash.
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.
