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,
It can be due to stasis dermatitis or neurodermatitis. 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.
