Lately, iam getting severe pain at the back of my left knee ( when i sit down on the floor & get up ) ?

Are you overweight?

It might be chronic bursitits; I've had that before and all it took was a shot of analgesic under my knee cap and i was back to normal.

Or you migh have strained a tendon or ligament.

Either way, if it hurts, you need to seek medical attention.

I have no schooling but i work as a physical therapist technician and we have lots of knee patients complaining of the same thing. In some cases it can be over use or a stressed hamstring tendon where the origin connects to the inner knee. Ibuprofen is good cause its a non inflamatory and the best thing to do would be to favor the other knee for a bit and work on moving your knee up and down when your in a chair or sitting on a couch somewhere where there will not be any stress on the tendon. once again i'm not a pro but i told you best i could diagnose good luck i hate seeing active people brought down by sensless injurys. sometimes crap just gives out for a bit.

You do not must have suffering to your again to have again crisis , from what you mentioned I'm definite you've gotten a nasty disc @ the s-a million /L-five and or L-four /L-five , you're going to have got to have a MRI to peer if this is a bulged or arthritic disc, In the imply time ,,,if you'll be able to preserve a small foot stool to place your foot up on whilst status in a single situation at paintings ,,this may make an international of change for any person who stands all day!

My Mother had the same problem and she had to have knee-replacement.

It can happen at any age!

After she had her knee-replacement, she done real good.

I can't even keep up with her!!

Please see a Doctor if you haven't already.

It's probably arthritis. It kicks in at different ages with different people.

i have the same problem.

i went to the doctor & they said i have cancer. =/
