Hi turbo5555, welcome to the board!
How long have you been taking these meds? Are you taking high-quality acidophilus at least two hours apart from the antibiotics? This is very important. Acidophilus replaces the good bacteria in your system. The best ones to get are refrigerated and have a high culture count (such as 9 billion cultures per capsule). Most healthfood stores have them.
Are you being treated by a knowledgeable doctor? Make sure your doctor knows you are having these symptoms.
