I noticed a niggling feeling to the left side of my chest last night i had been playing in a band so thought may be it could be to do with blowing my instrument but i have noticed it again this morning. I am thirty four not over weight and very active i dont smoke or drink. I am generally well apart from hormone related headaches. Its not a pain but feels like a little electric wire niggling.
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more. So follow these steps for better symptomatic relief. 1. Avoid heavyweight lifting and strenuous exercise. 2. Avoid movements causing pain. 3. Avoid bad postures in sleep. 4. Take painkiller and muscle relaxant Chat Doctor.  5. Apply warm water pad on affected areas. You will mostly improve with all these in 1 week. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
