when i imitate a butterfly swimming stroke with both arms in the air, as my arms pass my head i hear/feel a large grinding/cluinking noise that feels like it is coming from the centre of my back behind my upper chest. It also happens when i roll my shoulders together (forwards) if i really push them. does anyone have any idea what this could be and whether it is normal?
I did used to cycle alot with a heavy weight on my back and am concerned i could have damaged my back by not taking up correct posture
Don't think so. With me, if I put my left hand over my right shoulder and rotated my shoulder, I got a horrible clicking sound. Felt sort of dislocated until I did that. Was horrible
havent seen my gp, and yes the cause i'm guessing was a combo of heavy school bags, and doing a paper round on a bike that was too small for me with a properly heavy paper bag.
