My basement flooded. Stepped in, felt elecricity run through legs, got out. Immediately felt somewhat winded and both legs from knee down felt alot like when you lick a 9v battery. Subsided within an hour. Now hours later my left hand and arm to elbow and right hand are tingling, with intermittent cramp-type pain in left arm. Have history of hbp. What is happening to me, and do I need to be worried?
