Question: muscle spasms when laying down

 timothys2829 - Wed Dec 24, 2008 7:17 pm

Over the past year or so I have had involuntary muscle spasms on my left side, back near my kidneys and around to my middle side. Its really bad when I lay down at night and last for about 30 min or until I fall asleep and I cant tell of course. Sometimes it happens when Im sitting up as well. I currently take Paxil and I thought that was the cause. Ive been taking that medication for a couple of years now . I went to my doctor and he just gave me some muscle relaxers but that was not a solution to the problem. Any advice you can give would be greatly appreciated.

User avatar Hello --

While it's possible Paxil may be the cause of the spasms it seems unlikely, since there's not mention of this among the many reported possible side effects in the literature. Muscle relaxants don't always work with spasm, depending upon what's causing it. While dedicated muscle relaxants don't always work with this sort of problem, and if Paxil is doing its job otherwise you probably would be unwise to stop it even for a trial period. However, nocturnal muscle spasm (which is essentially what you describe) are often caused by low potassium levels. Your doctor might want to draw a blood sample for basic metabolism panel to see what your potassium level is, as some people seem to run chronically on the low side, and this can cause recurrent muscle spasm. If this turns out to be the case then the problem can be managed by prescription potassium supplement while the underlying cause of the loss is investigated.

I hope this is helpful. Please follow up with us as needed. Good luck to you.
