My mum used to go one of the homemade centre at JB.

She said the treatment is very effective for blood clot or blockage area but expect to get swollen for almost 1 week.

It can relieve your existing pain by putting different kind of "pain" at that area. Just like turning arthritis pain to surface pain instead.

Bear in mind, they don't fix your slipped disc but suppress the pain and allow faster blood flow at the stinged area. In some case, your injury heal faster because your blood flow faster to fix it.
