1)Based on the above information and facts could you please advise what my symptoms could be related to.? - Honestly, anything from strep throat to a urethral infection with strep (this is possible) or a cold, allergies, etc. You can get a urethral infection from normal mouth bacteria. You should definitely see your doctor.
2)What tests should I do? And after how long exposure?
You can test for gonorrhea, chlamydia, and NGU (infection in your urethra) at 3-5 days after the event.
You can test for syphilis at 3 months, though most test positive at 6 weeks.
You can test for HIV at 28 days with a DUO test. If it's an antibody only test, it's 3 months, though most will test positive by 6 weeks.
You can test for herpes at 4 months (this doesn't sound like herpes to me), though most will test positive at 6 weeks. If you get a sore that looks like it's fluid filled, see your doctor promptly, and have them swab it and type it. You can get genital hsv1 from someone performing oral sex on you. The number doesn't indicate the location, but the strain of the virus.
3) Main Concern I would say probably HSV2.
Your main concern should be everything, including your sore throat, which could be bacterial, though probably isn't an STD. Most of the time, oral STD infections are asymptomatic, and you'd get them from performing oral on a man, though it's possible to get them from performing on a woman.
1) for this question, you should ask your attending doctor.
2) common stds test and hiv test. There is a whole list of them, and each test have their appropriate time to take. It is impossible for me to list them down. So please ask your doctor, anyways you will require a doctor to conduct a test for you
3) you are at risk of all common stds, so no such thing as main concern
4) the doctors have left. Why dont u go visit a doctor so he/she can evaluate your condition?
