 [ Symptoms ] do i have hiv and could i have given it to my boyfriend  i had unprotected a few times i never got tested or had symptoms i have been dating a guy for 2 months and he is suddenly had a really bad flu i know that once you have contracted the virus it takes 2 12 weeks to get acute retrovirus syndrome which include fever fatigue and often rash headache joint pains swollen lymph nodes and sore throat he had all except the rash & swollen lymph nodes if he really did have the flu would not it be contagious no one else caught the flu from him [ Disease ] the only definite 100 way of determining if a skin lesion is a skin cancer or not is with a biopsy either the entire lesion  or a piece of the lesion is removed and analyzed by a pathology lab a skilled clinician like a dermatologist can give you a pretty good idea but a visual inspection can be wrong because of your family history of melanoma it would be wise to get it checked out
