please need some information on this subject. My brother had a knee operation about two month ago. H was in perfect health,after two weeks he had a very high feverand was admited to the hospital for all kinds of tests. He's was complaining about his joints being very sitff, and if was very hard for him to get up in the morning,he couldn't close his hand and couldn't stand too long. The doctors ran all kinds of blood tests and mri,ct,xray.But found nothing. Even the specialist. I would like to know if anyone had the simler problens. Please if anyone knows of any doctor that can help.Iwould be thankful. Also if you can direct me to some who has the same smptems.
