Sad how long it takes on the NHS. I fell heavily on my knee on concrete years ago. It was 6 months after referral before I saw a consultant, by which time the swelling had subsided and I could walk without a limp, but not without pain and flare ups if I moved it awkwardly. MRI...no chance. I was sent on my way. Chiropractic treatment didn't help, but recently saw a Body Stress Release Practitioner for something else and mentioned the problem. Don't know what she has done, but have no problems since.
