I had scabies 3 months back and it cured after taking treatment but one rash under my left breast is not curing, it was very tiny at the beginning but it is spreading now, it itches very badly but there is no pain ,not sure it is scabies or something else, doctors said you scratched it so it becomes big and they gave antibiotics and allergy, anti fungal, tablets, and creams but nothing worked, just got temporary relief only, sometimes redness and swelling decrease but it never cured. It changes shape and texture, Please help, it's been 3 months and no one is able to guess actual issue and root cause, please suggest if I need to take tests or something.

Hi , I have statis dermatitis... So my friend suggested me two creams Flutivate & Cetaphil Pro 10% urea lotion... I have even been advised to use moisturex Soft Cream... I have been using this moisturex cream for a year but the problem is it burns a little when I wash my leg after going to washroom..even I felt the hydration was not good enough. So I started using Cetaphil lotion ..now since it has urea it started to exfoliate my affected area...every time I take a shower I see dead skins on the floor.. but the hydration was top -notch Now my problem is if I stop using both of them my skin gets dry and starts to itch...and when I use it it exfoliates please suggest which lotion should I use?? What's the use Flutivate cream..does it calm itching in statis dermatitis
