Sorry to hear you're in pain. I had meniscus surgery about 6 years ago. It took me a good 7 months before I could play tennis again. I tried to come back too soon and got a bone bruise, which was worse than the surgery. And I wish I hadn't done the surgery b/c I now have severe arthritis in my right knee, which my surgeon neglected to tell me. I am very active, 55 years old, and still play tennis and paddle tennis, but I pay for it after. I am seeing a Dr in LA on Monday who has "a groundbreaking new devise for arthritis". Aside from that, I'm toying with the idea of prolotherapy to see if I can regrow some of the cartilage. My biggest fear is having a partial knee replacement, which could end my tennis days. I'd recommend seeing another doctor, and maybe just resting the knee - no running for a while. Good luck!
