Can lumbar spine problems (or spine problems in general) cause chronic twiching and/or spasming of muscles in the calves and feet?
My background: Posterior interbody lumbar fusion (L4-S1) 7 months ago, anterior cervical fusion (C5-C7) about 4 years ago, and undifferentiated spondylitis. Leg muscles twitch constantly, regardless of activities, worsen when I first lie down, but then settle down to mild twitching all night long after being in bed awhile. If I do any physical activities (walking on treadmill, stretching, eliptical machine, etc.) the twitching goes into severe spasms in my calves and sometimes in my feet during the night. Sometimes the calves will spasm when I climb stairs during the day, but I immediately walk out the spasm. On bad nights, however, I have to get up every 10 minutes all night long to walk out the spasms. If I don't exercise, the spasms are infrequent, but the twitching is constant. With exercise, the spasms are chronic on a nightly basis. At night my lower back frequently tightens or spasms, and in my sleep I'll arch my back and tightly lock my legs in a stretch to counter the lower back spasm, and it will wake up in the process; this may, at times, contribute to the leg spasms, but it doesn't happen everytime. I'm still having moderate groin and hip pain since the lumber surgery, but benefits have far outweigh the discomfort, and the pain is slowly but surely diminishing. The twitching and spasms preceded the lumbar surgeries and have not abated since the surgeries.
I don't have MS and don't seem to fit the pattern for RLS. I've taken RLS meds, potassium, magnesium, quinine, heomeopatic remedies, etc. but nothing help. Flexeril 3x daily will help when spasms get bad, but the side effects are pretty intense, so I stopped exercising for the sake of trying to sleep at night.
I would appreciate any insight you may be able to provide regarding back problems and leg and foot muscle issues. Thank you.
