 [ Symptoms ] i have rash on my leg it is only got worse it itches and feels hot [ Disease ] in my opinion first take an antihistaminic for example hyroxizine to stop itching second this can be either simple contact dermatitis or celullitis if it is celluitis you will need to have a strong antibiotic course of treatment i recommend you see a dermatologist to be safe contact dermatitis will improve on dose of 10mg hydroyzine every 12 hours also hydrocortisol cream should fix it hydrocortisol cream can make cellulitis worse so confirm your diagnosise at a dermatologist firstgood luck
