Hello, Thanks for posting on HCM From your description, you have most likely acquired an STD due sexual contact with the new girl. You will have to pay a visit to a doctor who will have to screen you for acquired active STD. Chlamydia or primary syphilis and gonorrhea are among the most common STDs to be acquired. You will need to visit your doctor as soon as possible for immediate evaluation and treatment. The other type of STD that you could have acquired is herpes. Examination of the lesions by our physician will help determine the type of infection you have acquired. There are readily available cure for the STDs with use of appropriate antibiotics. I will advise you immediately go in for HIV screening and later on repeat after 3 months. The new girl has to be treated too (i.e if you are able to get a hold of her). Hope this helps Dr Nsah
