hi my left side of the ear started ringing for about 10 days now, and it seems to be getting worse. i had a tooth infection on the left lower mouth (the molar) and the dentist prescribed Clindamycin, i took it for about 5 days before my appt 6/1/11 w/the dentist but left side of my cheek is still swollen still infected. but upon administering the 2nd shot, i felt it in the roof of my mouth then the room started spinning for about 15 min, my BP went up to 165/?, my extremities were cold & tingling, they gave me oxygen & gave me some glucose gel/watermelon & slowly my BP went down gradually, and spinning stop& went home after an hr or so. Went to another dentist for i was afraid to go back, 2nd dentist saw me 1 wk later, i needed to get my tooth extracted, so so scared that when they gave the 1st shot i started shaking and felt cold all over.. they gave me raw brown sugar and it helped right away.. And they were able to pull my tooth out & bone graft in within 10-15 min. The problem is i have ringing in my ears constantly now. I had it before i went to the 2nd dentist but it s getting worse, i can t sleep at night, seems to be worse when i m sitting or laying down.. I don t know if they hit a nerve or if i still have infection...
