<human>: sir, I am feeling burning/pinching and twisting in my nervous and muscles in left side and in chest area. I have shown to doctors, they did ECG and told that it is not heart problem...and asked me to apply pain gel to reduce it..but the problem persists...please advise..
<bot>: Hello! Thank you for asking on Chat Doctor! Your symptoms seem to be related to a musculoskeletal pain. Inflammation or an electrolyte imbalance can not be excluded either. For this reason, I would recommend performing further tests: - PCR, sedimentation rate for inflammation- blood electrolytes including calcium to exclude possible imbalance. Meanwhile, I recommend taking ibuprofen. I would also advise you to closely monitor the skin in this region for possible eruptions. Shingles can cause similar symptoms before eruptions.  Hope to have been helpful! Kind regards,
