I'm a 19 year old male with fasciculations primarily in my right lower leg, starting in mid-March of this year. They're almost constant, and happen in several places throughout my right leg spontaneously, and consistently. It started in my right calf, but has since progressed to happening in other places, such as along the entire right side of my neck (off and on), in my chin/lower lip, occasionally on my abdomen, and as of last night my right bicep,(it woke me up) and forearm. My hands also quivers when I grip.
I also have other symptoms, such as if I flex my right leg, the muscles of my calf cramp up, and/or quiver, and take a while to release. If I raise my foot and flex the muscles in my leg, my foot is held in place and slowly drops as the muscle relaxes. Occasionally, if I point my toes down, they cramp and are stuck pointing down. I also noticed (and measured) last night, that my right lower leg seems much smaller in circumference, and is indeed .5-1" smaller than my left calf.
I have two herniated discs at L4-L5, and L5-S1, with loss of light sensations on the lateral aspect of my right lower leg. I have had an MRI of my L spine, brain, an EMG, and EEG, as well as blood work (including magnesium, calcium, thyroid function, and Lymes disease - no results yet.) No known family history of neurological disease.
During the EMG of my right lower leg, the neurologist inserted the needle into a muscle that frequently twitches, and there was no activity, and he seemed baffled.He then ended the exam. That same area of muscle now seems sunken and soft. Possibilities?
