Very interesting info because in may my left knee buckled and gave way, both knee and feet swelled, i went and saw the doctor and it was sprained and also thinks i have RA besides Osteoarthris another thing from birth

Then to top the lot with pressuring my right leg that one buckled the same and i was layed up for over a month and still now each day i have to spray them with cold freeze.

Rheumo's had both knee and hips x-rayed but waiting for an appointment.
