I'm going to try to make this as short and sweet as possible. Back in February, I had a really bad case of tendonitis in both of my knees from muay thai. I saw the doctor and took ibuprofen, iced my knee, and wore support for many months until most of the pain went away. The tendons on the back of both knees where the hamstring is also feels a little tight at times but is bearable. However, my left knee still has ongoing pain, but only while I'm sitting. The burning sensation and spasm sensation is gone, but it gets a really tight feeling and starts aching. I got an MRI and it says that nothing is wrong. The orthopedic surgeon told me that there was nothing wrong and my quadriceps are just weakened. He told me to do physiotherapy. I did it for about a month and nothing really improved. It still bothers me a lot. The doctor was kind of young and I'm kind of skeptical about what he said. Just wondering and the sherdog community has any advice or similar experiences and can share your knowledge with me. Thanks in advance.
