If you're having those symptoms, it makes sense to stop. Be sure to call your doctor and report what has been going on. Long ago I took Sulfa for bladder infections repeatedly over several years, and one day my throat closed, and I got hives all over my body. So there's an example of an allergy after doing fine on the drug for a long time.
Call you doctor for sure...see what he/she thinks you should do.
