I used to get itching Allergies on my hands suddenly and they used to disappear as suddenly as they came within a few hours. However, off late the allergy has now spread to my hands and my legs and it keeps itching post which I get red rashes/bumps all over my legs and hands.Once the itching stops it leaves with a burning sensation. I recently completed a 5 days allegra course but it came back again in a week. Now the itching doesn't go on its own like before...it stays for longer like 2-3 days. I got an
LFT test done and the report was normal. Not sure what this could be. Can this be a sign of a serious illness? Attaching photos of my hand and leg with the rashes.
