Chronic Pain :: Stiffness And Cramps In Legs

For the past years, I've been taking 5 tabs of Methocarbamol 750 mg. along with 600 mg.(6 caps) of Gabapentin during supper and right before going to the bed, because I have not only leg cramp and spasm but also nerve pain on my legs. Those two meds. have been alleviating my pains that mostly occur during sleep, ... specifically during early morning hours before getting up from the bed.

Prior to those two meds. I had an excruciating and unspeakable pains that waking me up in the middle of the nights lasted about 10 minutes or so. Furthermore, the pains made all over my body sweat like taking hot bath, because of excruciating and unspeakable pain. Those nights, I self-exercised stomping, and often back and forth legs on hard floor in trying to subside the pains.

However, despite maximum doses of two pain meds., I still have been experiencing 'stiffness' along with 'pain' on my legs, some mornings before getting up from the bed.

Is there any good meds. for me more to manage and first of all control muscle spasms and cramps on my both legs?
