Big Sister's Bad Knee

My eldest sister came by last night to pick up something mum sent back to her.  She was struggling to get up the stair.  Her right knee is painful.  I feel sorry that she is not in the complete physical shape.  My wife think it may be the spine as it is possible that an adjustment can reduce the pain.  She had this experience before.  Anyway, I just called my sister and she has no interest in trying out a chiropractor.  So that's that.  No point trying to convince her as she had an injection that solved her problem before.  What she does not realise is the injection masked her symptons and did not cure her knee problem.  Chiropractor may not solve her problem either but it is good to eliminate this as a possibility.
