I just got back from my doctor appointment to review my MRI results and found that my knee pain was due to major inflammation (which is now better

The doc informed me that it looks like certain parts of my wrist are wearing down, I may have some torn cartilage and my marrow looks like it's not doing so well staying either. My doctor said that I am too young (19) to have a degenerative disease usually, but he wants me to come back in four months and check to make sure nothing has gotten worse. The good thing is that it's not that bad, pain wise, anymore. It gets a little sore every now and again, but other than that it's not that bad.
Please pray that this doesn't get worse than it is. Oh yeah, I also have bronchitis so please pray for that too.
Thanks in advance!
