I have had horrible knee pain in both knees. Pain was so intense (hard to walk) and nerve pain even when resting. I did PT and still was sore thereafter - exercises and electrical stimulation. It took me about 5 mos to be able to walk without constant pain. It comes and goes now but not near what it was. I did not have to have the shot but that will probably be an option in future as have the osteoarthritis there. Just wanted to let you know it can settle.
