In an effort to reduce my migraines, which were exacerbated by my advancing carpal tunnel, I requested my doctor to give me muscle relaxants. Since you put me on a low dose one, which seemed to help for a while.
After a couple of years of being on the muscle relaxant, I started having bizarre intercostal muscle cramps, at random. And after consulting with my doctor, I learned that was not uncommon. So I began cutting back On the muscle relaxants. That did not reduce the cramping, Nor did stopping taking it all together.
I've been off muscle relaxants for Months now, and it's only just now starting to abate the cramping. But at least It is starting to lessen.
Today, when I woke up, I found a new symptom. Of what, I'm not certain. But I appear to have sore muscles all the way from my waist, on the right side, down to my knees. Due to some pre-existing numbness in my right thigh, I did not notice sore muscle area in my leg at first. But when I started examining myself, I discovered it.
