Please help me with my knee pain

[Eric_Hook]

Can you help me, please.  I am a 48 year old male and I play badminton and squash about 3 times a week.  I weigh 185lbs having just lost 30lbs.  The problem is in my left knee.  For a start I get intermittent clicking which in itself isnt that painful.  Then all of a sudden the clicking stops (quite often during exercise) and then the pain sets in.  I get a very sharp constant pain on the inside of my knee which when touched feels bruied and sore.  My knee also feels stiff when I walk.  If I push my knee fron behind i get a jolting pain through the knee.  If I am in bed and laying on my side when I try to turnover I also get a terrific amount of pain in my knee which I can only describe as a "hot needle" type of pain shhot through the knee.  Day by day the pain will slowly deminish until the next episode of the clicking which sets it off again.  I have seen a doctor but as usual by the time i got to him the pain had gone and he couldn't find anything wrong with it so he told me I had sprained the ligiments and that I would be alright after I had rested it.  Well guess what I have rested it, it has played up again and is as sore as ever.......any ideas

go to an ortho doctor - have an xray taken to rule out arthritis.  also have your doctor do a "Mcmurray" test (i forget how to spell it) - ortho doctor should know what it is. that should show if you a have a torn meniscus. thats what it sounds like to me
