hi, i have been experiencing shortness of breath, increased pulse rate, sore throat, headaches, mouth sores recently. My tests were negative: ECG, 2D echo, chest xray, cbc (HDL/LDL are ok). Only minor findings are: borderline uric acid, borderline ASO-titer (streptococcus bacteria) and mild skip beats. My cardiologist and pulmonologist says i am healthy. However, i have been tortured by this feeling for the past 7 weeks now. I was initially given antibiotics by my cardiologist, for me to take for 3 months. However, after consulting an Otolaryngology (EENT) and another cardio, they advised me to stop the antibiotics. I have observed that while i was taking the antibiotics (4 weeks), my shortness of breath decreased, mouthsore gone, but still my pulse rate is high. Then when i stopped the antibiotics, all these went back.. with greater intensity. What is wrong with me?
