Dear Friend.
I read this some where during my medical school and found it true :
"A Medical student sees all the symptoms in himself, of the disease he reads"
However, you had a risky play, look HIV and Syphillis don't spread by touch. As you said she just touched you with no kissing and intercourse, means you had no contact with the body secretions.
So it is unlikely to contract HIV, Syphillis this way.
The problems you mentioned, might be because of a
sore throat, upper
respiratory tract infection.
Bruxism can be found in normal persons too, or sometimes it may result due to excessive pyscological
stress, that you are taking.
Here, i would say, don't repeat such activities again.
And to be sure, get yourself tested. Go to a
STD centre in your medical college and get tested in confidence.
Stay Healthy
