I have used a TNS unit, but it was really hard to keep the batteries charged all the time. I haven't tried anything that has been inserted surgically. This is really getting rediculous not being able to lie down. Yesterday the spasms started at about 3:00 in the afternoon. I've maxed out my pain relief doses and still not a bit better. I tried stretching and moving, but it won't go away. I guess I just have to wait until the muscles get tired and loosen on their own.
Thanks for the suggestion. I'll ask the VA doctor when I see him on October 30th (soonest I could get).
