amoxicillin only helps of you have a susceptable bacteria. it will not help all infections and will not help viral infections at all. since i have no idea what you have or what your doctor is treating my suggestion is for you to contact the medical provider who is treating you -- one who is familiar with you and your case -- for advice.
i am on amoxicillin 500 mg and i still ache all over and have the cold chills tired and i am weak?
