Patient discussion about fasciculation.

Q. Female 57old has fasciculation.Started 3 months ago as a twiching jumping beneath the skin mainly legs & It started with the legs(lower back parts),more so in the right side.Lately also in the hand(mainly arms ,more apparent on the right).There is also a sense of tensed muscles(sometimes painful because of prolonged tension),"pins &needles"and often a sense like a low electric current going through the limbs(mainly legs,sometimes arms).Also sometimes they tend to feel a little numbness and "fall asleep" real easy.She first noticed it only in the morning when she woke up,both legs lower part,back side.About 2 weeks ago it started not to go away,but stay with her all day and night.When she walks it is a lot less noticeable. All the blood tests,vitamins(D,B12,Mg,Na)are OK.TSH(Thyroid)&CK are OK too.Creatine, Calcium,OK
