The armaid is interesting, but limited. I carry small hard rubber balls wherever I go. The ball by itself enable you to reach more places. I first used a tens unit at my wifes work. Amazingly she works at a PT now for 25 years. It helped but not consistent enough. So I bought a tens unit 7000. Punch that into google and Amazon has them for 30 bucks. I use two at a time, because it usually 30 minute treatments. PT`s use just a constant charge, I have since gone to a pulse type setting. It is more like a work out. I usually probe from my tricep to the fore arm or to the meaty part of the palm. I actually use it all over my body since I own it. You really just need to experiment as each person is different. My fascia was sticking terribly and sometimes it would take over an hour before I could move again. But 30 bucks sure is cheap vs trips to the dr office. So good luck.
