Experiencing Severe Side Effect- Please Help

Hi, I have been taking penicillin for almost a week now for a tooth infection and i am having problems iwht infrequent urination (to the point where I am not urinating at all anymore hardly), also agitation, confusion, weakness, completely liquid diarrhea, flu-like symptoms such as lung congestion and headaches. None of this was happening before i started the penicillin, and I looked it up and it says if you have any of these symptoms to cal your doctor immediately but I do not have one. Should I stop? I am worried if I stop taking it that I will have problems with the infection in my sinuses and tooth, but if I don't stop I am worried that I could suffer kidney failure or something bad. Please help me.. this is getting bad! :(

Whomever prescribed you the medicine is who you should call.  Or you can go to the county health department clinic as a walk-in and you can see a physician that day for very little cost and he can advise you.  In some phone books a hospital will be listed and will have a section called "Ask A Nurse," and you can call them, or you can call the Poison Control Center, which is in the book too.  But no matter what, you'll wind up going off the penicillin and another antibiotic will be substituted, because it sounds to me like you had an allergic reaction and that drug is most definitely not one you should be taking, now or in the future.
