Today I did my usual personal trt pin with advised mast e and tne dbol. Now , not sure if it's related,but a silver dollar size area above tailbone feels sore and bruised. No I did not hit it on anything. Could this be some small sciatica inflammation that went up to there cause I do got slight pip on el glute. just weird and no clue why just in that spot.any ideas? I'm outa dr advised pain pills to sleep.
