I have dupuyten s contracture, shoulder impingements due to my bone structure, and possibly carpal tunnel, I have electrical shock in my hands when I turn a water faucet, pain in the palms of my hand, numbness and almost constant tingling in my fingers and thumbs, motrin helps all symptoms. The numbness and tingling is worse in the mornings but is present all day. I think my hand problems are due from my shoulder impingement. I am scheduled for a nerve conduction test, but just wondering can shoulder problems cause my hand problems??? My age is 54 and I have never done repetitive work
