Welcome in H.C.M.
I came to know that you are having throat infection
with swollen tonsils and pain on degulitition. Recently you have treated for vaginitis
Now you are worried about Strep throat
infection and also for STD.
Your throat infection should be investigated by Culture and sensitivity of throat swab to rule out strep infection and to know about causative organism along with knowledge about most effective antibiotic.
Since you had vaginitis so nobody can clinically rule out STD. But this confusion may be solved by VDRL
I hope your query is explained well.
