Hi
Welcome to the MedHelp forum!
Electric current like feeling can be due to side effects of certain medications. So stop this drug if you are taking one and see if it helps. It can also be due to fibromyalgia, Vit D or Vit B12 deficiency or peripheral neuropathy of diabetes and hypothyroidism. A pinched nerve can also be the cause. Lyme’s disease is another possibility.
Since I cannot examine you and know other related conditions you may be having, nor is a detailed history possible on net, I have listed the various possibilities that should be looked into. Please consult your PCP for primary examination followed by proper referral.
Take care!
Considering your history of MVP, i think this warrants in the very least, a trip to the cardiologist. Changes in blood pressure after lying down and getting up to quickly, or PVC's, any number of things can be a hidden culprit. You definately need to consult a physician or health care proffesional.
