My son is 29 years old and has had problems with his right knee for years, pain and stiffness. He's quite tough and did'nt see a need for a dr. because it has been managable.
About 2 weeks ago he woke up in the middle of the night in severe pain with the left knee and could'nt move it even to turn over. He finally did, quite painfully and using his hands to move it. From that point till now he can barely walk on it.
He's now been to the family and orthopedics dr.s, had x-rays, an MR and blood work.
He went in this morning for results and was told they found nothing!!   
These dr's have been able to actually see how much he was suffering and have had him on loratabs to help manage the pain.
We are all flabergasted at the diagnosis, and are at a loss. He truely is suffering and needs help.
Mind you this is a person who never gets sick and I know he hasn't been to a dr. for anything else in at least 10 years.

Do you have any clue or ideas that we could have dr.s look into??

Will anxiously await your reply.
Sunny
