i went to the dr. due to a herniated disc. i received an injection in the bottom. before the nurse took the needle out i statred to feel funny. i thought it was because i was thinking about it too much.but before i could walk all the way to the waiting room i felt nausea and faint. i sat down waiting for my release papers. i stood up asked the recpt. if i could lay down some where. i was trying to breath normal, but was starting to faint. i told her i was going to faint, she went to get the dr. i had then passed out. i believe i had an allergic reaction. i was sweating,cold and clamy. i think i was out for a few moments. woke up on the floor. i did start to sneezing, scratchy throat. i did lay there for a while. they checked by blood pressure from time to time. aftr bout 30 min i was able to leave. had allergy syptoms all night but seem fine now.
