Hi, welcome to our site. I am Dr Saumya Mittal.
Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query
This is probably a muscular
contusion where the blood from the rupture of vessels collects in the muscle. This causes
stiffness of the muscle and lots od pain on initiating movement, that subsides a bit when it is continued.
I would have suggested x rays of affected parts to any patient of mine to make sure there is no damage to the bony component.
I think, for now, have some painkillers, try a crepe bandage, and have plenty of fluids.
