I have a similar situation, which seems less serious than LZ. In fact, this situation has nothing to do with playing ball and push-ups, mainly because you hurt yourself while playing ball, such as hitting your elbow with your arm straight and hard, which is easy to hurt your elbow. I've been hurt before.

PS: I suggest the landlord not to give up basketball. First of all, if you don't play basketball, your joints are not necessarily silent. Secondly, I think life lies in exercise, and it is easy to have problems without exercise (provided that you don't work too hard). These are my personal feelings and experiences. Give points, hee hee.
