Both knees have started to swell and ache. Lyme tests neg, arthritis test all neg, no gout or lupus. My feet may ache today and not tomorrow, then be so bad can harldy walk, mornings are very hard to get out of bed from stiffness, wake up with arm in severe pain from laying wrong. Any suggestions for tests that i should request or ideas as to what to ask?
