Glad to hear from you my friend! Glad to hear your back is better, ouch on them hips. I am on a unit similar to your TENS unit you were using, called H-Wave for my back and knees and neck and shoulder and whatever else that hurts. Getting ready for Christmas around here, I do hope you are taking it easy and have a great Christmas season, ever! Hope to talk to you real soon, hang in there. Cheers!
