Chest pain anxiety?? Reassure me :(

hey, the doctor have told me i have chest wall muscular chest pain. i had this going on for 8 months and it occured when i stretched my hands backwards, bended backwards. Anyways, now i can feel that this pain is gone when i stretch, but now the chest pain is like when i take deep breaths/sneezes etc it occurs. 

Is this still only muscular? Since it hurts when i breath, i've experienced the deep breath pain before also, but now it came back.

Concerned

Have you pulled the chest muscle groups by streatching, it may be you need to stop streaching backwards and allow the tendons and muscles time to recover, if you keep streatching it may take a long time to get better

Same here. A whole bunch of symptoms. I can go on for hours.
