Hi there. I am 22 years old and have been healthy my whole life. I am a full time babysitter (nanny) which means I will almost always catch whatever the 3 kids I wAtch catch. About 2 months ago they all came down with strep throat. Their parents suggests I get tested too ( I was feeling a little under the weather but nothing major) my rapid strep test which they Said was about 85% accurate came back negative, and they didn't think I should pay the extra money for a culture because I had no fever and no sore throat. Just muscle pains and swollen neck glands. 2 moths later (the other day) I went back to the doctor because I simply just "didn't feel right" and my muscle aches turned into really bad joint pain all over. They decided to test me for strep again and it was indeed positive. This is my 4th day on amoxicillin and my joint and muscle pains have not subsided. Mainly in my legs and feet. Sometimes hands. I am very anxious and worried that this is something more severe. I am suppose to be taking these antibiotics for ten days I'm just worried they won't do the trick. What do you think?

Please, need some expert advice
