The drug syndrome/

Having spent several months on a strong penicillin drug for my leg my surgeon recommended coming off it a few weeks before the operation so he could take a culture to check any remaining infection and issue "a better" drug to clear it up. In the event I've ended up back on the same drug, but already my dizzyness has returned, as has my indigestion, stomach upsets and erratic blood sugar readings, all had stabilisedin the few weeks I was drug-free.  My research reveals these are common side-effects of the drug so I'll seek medical advice after the weekend.
