<s>[INST] I have a soreness in my back and chest on the left side only. I saw the doctor and had an EKG and a check x-ray which were both negative. He prescribed an antibiotic which I took for 5 days the back pain has went away but I have a tightness in my chest. He believe I have a virus that has settled in my muscle. It is not related to my breathing. It seems to be a muscle spasms that happens when I am not active. What should I do to heal? [/INST] Howell come to ChatDoctorI really appreciate your concern, if this is the muscular pain of chest region then it may not be due to virus, but it could be due to hyperacidity because it is the common condition seen, here in your case the EKG and chest x-ray are normal one, so the possibility of acid reflux disease is more likely, and I would suggest treating this condition with Tab Omeprazole 40 mg once in day and Risperidone 20 mg once in day for three weeks, try to low down the stress hope this information helps. </s>
