Acupuncture Pillow Massage Yoga Mat Body Stress Pain Reliever Set
I suffer from splenius cervicus and this acupuncture mat does WONDERS! For me the spikes feel GREAT. Very relaxing and well worth it.
It won't do miracles for you, but it will increase the blood circulation where you use it.
I use it mostly without clothes on back, but be aware that any sudden movement might scratch you all over.
After 10 or 20 minutes you will feel more relaxed because of this item and because you have to lay on the floor too, and that also helps.
