I am 34 years old and my doctor diagnosed me with Rheumatic Fever 5 months ago with my ASO titer at 253. He then asked me to meet a couple of specialist and meanwhile started giving me penicillin injections. My echo, ecg, and other tests were fine, so the specialist told me that I do not need to take any more penicillin injections, but my family doctor says one has to take precautionary medicines for atleast 5 years. He asked me to do my ASO again next week to see if it rises again without taking injection and I already have started getting fever (99). Please let me know whether I have to take injections or tablets for years now.
