I totally sympathize with you Denise! If it's a muscle spasm, whether the primary cause or has resulted from favouring the area where you have a bone spur, it can take a few weeks sometimes to remedy itself.
We were in Newfoundland a couple years ago and in pushing the car door open one day, my muscles in one shoulder went into spasm and it was tortuous! The first couple nights I took enough pain meds, muscle relaxers and sleeping pills to down a horse and still couldn't even doze off. Way to ruin a holiday that's for sure. I think that one took about three weeks to ease up all told.
I also had another experience a few years back with getting a spasm in my jaw muscles on one side and could just barely slip a flat teaspoon between my teeth. I think that one was the result of incessant tooth grinding. After a week I started getting worried that it would never 'heal' and I'd be sipping every meal through a straw for the rest of my life. If I remember correctly, that also took about three or four weeks to recover from.
I sure hope that you're able to sleep finally a bit. It's a dreadful pain to deal with isn't it?
