I have severe allergic reactions to a lot of antibiotics, some of which have given me Stephe-Johnson/TEN Syndrome, which is very dangerous (too long to explain, please look it up). I currently see an Allergist/Immunologist and try to only take herbal supplements or homeopathic remedies. So I definitely would suggest seeing an Allergist and I would get rid of your doctor and see someone who is more compassionate and helpful. Good luck!
