He is under the patella - hes so much strong and especially when I jump or just running.

The second thing is the soulder, 3 years ago I fall from tree (the height was around 2 metres or 2.5) so when I falling my hand goes automatically behind me, just catch your neck behind you and u will see. I ignored that I should go to doctor, however the pain dosent exist but he occur some times, and I wanna rid of this !. He is very painfull if I want make round stretch my hand like circles stretching cloackwise direction, whenever I wanna try some flip I feel pain from my fingers to my shoulders. I cant ever take my hand behind me and stretch them very well cus I feel like that is blocked.
