Help plz!

So, I’ve had this rash spot on my inner thigh for weeks now. I’ve posted once before and got told it was severely dry along and to use lotion...I have been and there’s so progress! It itches sometimes like usually when I go to bed or am hot!

•It’s no where else!

•been there for weeks

•lotion does NOTHING

•and itches sometimes

•doesn’t hurt

(I’m sure y’all prolly know my mind immediately goes to stds lmao)

But...at the moment there’s no doctors open to see me because the Corona virus.

My friend is a nurse and said she thought it was allergic dermatitis...and to put calamine lotion on it which I plan to try tmr hoping for results!!

Any advice or maybe assumptions of what else it could be...or help ease my mind and rule out the worst (std)!!!
