Almost constant twitching in left calf and some in right. i have mild lumbar scoliosis with hypertrophy and spinal stenosis. could this cause this?

Twitching: How long has this been going on? It may be ok. It is a common symptom. Twitching could be caused by some changes in your back, in particular if there are changes around S1, which is a common site for stenosis. What is more important- are the calves strong? Do they seem like a normal size? If you can stand up on your toes/balls of your feet, it may be ok.
