Hi,welcome to HCM, I am Dr Das
Firstly, CD4 count denotes number of T cells which has ability to fight against any infection. Now, in case of HIV
, the count decreases below 500 and it causes inability to fight against infection.
Your CD4 count is within normal limit. If all other tests are ok then wait for wound healing
I suggest you to do a blood sugar test, and a good antibiotic. Thank you.
