Hmmmm. I read your posts, and all your symptoms, and the nails, endocarditis, and joint issues sound very much like the symptoms of lupus. If you type into google "lupus nails". See what you get. Try to find an image. See if the pictures look like your nails. Endocarditis is very common in lupus. Mainly attacks the mitral valve. The joint pain, popping and fleeting pain is classic lupus. It's very common to not have any redness or swelling with the pain.
It's interesting that your labs came back fine. Can you tell us which labs you had done? I'm curious to see if your rheumy is looking for lupus or something rheumatic.
How do you feel otherwise? Any additional fatigue, foggy thinking, headaches? I don't want to all of a sudden freak you out. But it's one avenue to look at.
Take it easy!
