Muscle Pain Around Joints

Howdy all. Is there such a thing as "the muscles/ tendons right around the joints... On 1 side of your body" problems?

My foot, knee, elbow, wrist, and shoulder, all on the left side of my body, have injuries. Its not the actual bones that hurt, its the muscles/ tendons around the bones that hurt. I can account for how each of them got injured. Its not even that they hurt, its that injuries on this side of my body dont seem to heal. None of them are extremely serious in that I can still lead a pretty normal lifestyle for the most part. Something probably worth mentioning is I also have a bulged disk in my back on the left side. I forget which number it is, but its the mid - upper section of my back, not the lower as usual. All ideas are appreciated.
