Honestly, I don t know, I m in so much pain in my throat. I ve had this since Thursday while we were in Disney world. Went to dr on Saturday, said I had strep throat, an upper respiratory infection and a fever. I am in so much pain, the only thing that works is tramadol, which I had left from a back injury. I m desperately trying to see my back doctor and probabably my PCp again as soon as I can stand to drive. I asked him to give me 30 to get me through. All he gave me was 875 mg of amoxicillin. From the cough, I m even in more pain. I ve never had a sore throat like this with a headache that won t stop pounding. I need a cough med so bad so I can sleep. Since all I can do is wait until morning to get a new prescription or additional medication, don t you think it s best to wait.
