Hi Linda - as redcrx has kindly posted a link to my daughter Wispy 68's thread, I thought I'd update you.......
My husband's had ongoing pain in his neck & shoulder for some time, but our doctor advised him against having physio, as it could make it worse, although he did suggest trying acupuncture.
However, he recently bought a Tens machine from Lloyd's Chemist (own make) �14.99 & says it's certainly helped ease the pain, enabling him to ease off the painkillers!
Hope you find a solution for your back pain & feel better soon.
