I am 29 years old. I have a strange problem with my joints. The only ones I've ever actually injured was one knee (stretched ligaments & soft tissue damage), and one elbow (fractured). My joints do not swell (with the exception of the one knee), and they do not get warm. They just ache and snap. My wrist pain is usually brought on by lifting something with a little weight to it (does not have to be heavy). But I can't explain the elbows, ankles, and hips... Sometimes even my fingers get this same feeling. Like it's right in the tendons, or in the bones... Yes, it can keep me awake at night, especially when I have it in my hips (can't get comfortable...) I am too young to have this kind of problem (in my opinion), so what could be going on??? There are a few other things bothering me as well, but I've dealt with them so long that I've just learned to live with them. Sooooooo tired all the time... I could wear my coat and slippers all day long and be quite comfortable. For whatever reason, I've noticed that my temperature is usually low, and in the evenings, I always have a low-grade fever for a little while. Any ideas?
