Transcutaneous Electrical Nerve Stimulation.
It has four pads that you put around the painful area, plug in to the mains, and it stimulates nerves and causes muscle contractions, and this seems to reset the pain threshold or calm it down. It seems to work best on nerve or muscle pain.
As strong painkillers make me dopey, I find this is often the best way to cope if Ibuprofen doesn't work. It works well on back spasms too. My machine also has a massage and heat programme.
