I am not a medical doctor but I have a little information for you:-
The medical term for bone spurs is osteophytes, and they represent an enlargement of the normal bony structure. Basically, osteophytes are a radiographic marker of spinal degeneration (aging) and are by and large a normal finding as we age. Over the age of 60, bone spurs are actually quite common.
The term "bone spurs" is really a bit of a misnomer, as the term "spurs" implies that the osteophytes are "poking" some part of the spinal anatomy and causing pain. However, this is not at all true. Bone spurs are in fact smooth structures that form over a prolonged period of time, often causing back pain.
From what I am reading into it, it means that it is normal wear and tear. From what you describe in muscle strength loss and burning of same, this definitely sounds fibro related. Maybe a bit of arthritis in your hips?
The tmj diagnosis - I had this and it caused me a lot of pain, then just my luck I was involved in a car accident and it became worse. Different things i.e. gentle exercise of the jaw, not forcing your jaw open say at the dentist surgery, and so on work differently for each person. It is a case of trying to devise something that is best for you.
As I say these are only my own ideas. Someone else might be abe to help you further.
