My wife is experiencing neck pain now and then, what can be permanent solution for the problem. She went for Physiotherapy once, it came down after the treatment, but came back again later. She cannot go for the Physiotherapy treatment very often as its is a costly thing. She cannot bend her neck when there is a pain, she is using hot pack to get some relief when she feels the neck pain. Please suggest me what can be the better treatment for the problem. Can yoga help in curing the pain?
