Welcome to HCM.
Of course oral sores over soft palate
can occur in HIV
disease. Herpes simplex
infection, yeast infection, aphthous ulcers
are common to get with HIV disease. At the same time all that appears in mouth are not necessarily due to HIV. Above said lesions can occur with anybody who is not having HIV also.
If you think that you are at risk for HIV, test yourself for HIV to rule out the same and consult your physician and get cured.
Get well soon.
