Side effects of penicillin?

You may want to ask your doctor, however, you must know that everyone reacts to drugs differently...especially penicillin. Penicillin is derived from another type of bacteria, which is why in many cases of people being allergic to it, there are many alternatives. Medical technology has come a long way. Also, through infections alone can cause very adverse affects on your body. Even a small ulser can cause swelling of the glands, headaches, nausea, etc. Check with your Dr., but remember...he went to med school for at least 6-8 years...he should know a little about something.
