Searching for a cure to end my muscle spasms. They began in 2016 after pulling weeds. Lost the feeling in my right big toe. The spasms start in the toes, move up my calve and continue to my hamstring. Following L4-L5 lamectomy/discectomy on Sept 1, 2017, I regained the feeling in my big toe, but the spasms have never gone away. They keep me awake at night.
I assume that you had a disc herniation at L4-5 which caused both numbness as well as muscle weakness of the L5 nerve distribution which lead to your surgery. If your spasms are in this same leg, the cause could be nerve root chronic injury with chronic muscle weakness. If I am correct, the weakened muscle will cramp if overloaded. Muscles can also cramp without nerve injury due to metabolic changes and vascular insufficiency.
