Thank you for your questions.
Unfortunately, we are not able to diagnose symptoms online. If you are concerned about symptoms it is best to have them check by a health professional.
A sore throat is not a typical symptoms of an STI. It is more likely that this is caused by a cold or similar virus. You say that you have done your testing for STIs and they were all negative, so as long as these tests were done after the Window period had passed, you should be able to put those out of your mind.
There is no standard testing done for HPV in British Columbia and so the only way to know if you may have been exposed to one of the strains of this viruses is to develop warts or if you were a woman, to have an abnormal PAP test.
As you did not perform oral sex on this person, it is very unlikely that what you are experiencing in and around your mouth is related to HPV. Warts caused by HPV are different than blood blisters; they are usually a raised growth of skin that can have a rough texture. Warts do not fall off, but the skin can return to normal once the body cleared or surpressed the virus (this usually takes a number of months). It is also rare for warts related to HPV to develop in the mouth.
