Hi I m a 25 yr old male, lately having frequent urination and muscle twitches in shins along with less than restful sleep. My caffeine intake is pretty high but the urination happens about every hour or two. I am a smoker and recently had an episode of nerve pain in my feet that lasted about a week. Other than the two bad habits I m fairly healthy with no history of major illness, disease, and next to nothing in genetic background. Just wondering if this could be anything I should get checked out. Thanks!
