XXXXXXX 3: Full STD panel all negative

July 8: Lymph node swelling under right armpit, Doctor gave Loratadine for allergy and Fluconazole for mouth infection.

July 10: Did 2 tests - HIV1 RNA Qualitative test and -HIV AB/AG test; both negative.

Today the problem of my mouth still exists, I have been taking those medication, there is significant change since that only one tablet of Fluconazole, but me doctor said more than 1.

2. HIV 1&2 have more are less the manifestations, but HIV 2 is less virulent than HIV 1 and have a less severe course with a lesser possibility of transmission to sex partners and mother to child transmission.

My son has a raised rash on the backs of each hand and elbows, which he has had since yesterday. He has had a similar rash many times before when playing in grass. He has been playing soccer on grass turf all week. My husband gave him one loratadine (active ingredient - 10 mg) tablet 2 hours ago because he could not find benedryl (diphenhydramine hydrochloride) at the time. I have the benedryl, can he take some now (2-4 tablets - 12.5 mg). If yes, how much? If no, when can he take benedryl.

Hi. My Daughter has a cough and rash on her forehead (tiny bumps) no fever, no itch no pain no other symptoms. Plays well, eats well and sleeps well. She has been taking Claritin for spring allergies and started on mucinex yesterday to keep her cough loose. I m puzzled by the tiny bumps on her forehead. The community pool just opened this past week so could it be the pool water?
