After having Rotator Cuff surgery (5/16/11) my left arm hand and fingers (little one and the next one) started to really bother me. The fingers felt as if they had been asleep and were just waking up (all the time). They were numb and I could not feel hot or cold. I scalded my hand. I had to stop cooking and many other things. Then I found Tric! After three treatments my fingers feel so much better and I can feel hot and cold. I am able to cook, wring out dishrags and thread a sewing needle! My upper back and across my shoulders feel much better also. Thanks Tric for knowing how to make me feel better.
