I have been doing it for the past 2 months. 30 mins of acupressure followed by acupuncture. On 2 occasions my neck and shoulder were stiffen up so badly like a rock, it did help loosen up the knots and relieve the stiffness and pain. As for my back to hips area, the pain is reduced and can sit and stand for longer time after the session but feels worse, more tired and pain the following day. Some may feel slight dizzy (once for myself, on empty stomach) and nausea right after the session also. These side effects are common for some people.
However, like all of you who responded, this relieve only lasts few days, for me the maximum is 5 days and the pain becomes unbearable that enticed me to go back for another session, feels better for sometimes 3-4 days and repeat. I realised that the pain is in control especially those spots that were targetted.
I have been telling myself to stop spending this money on something which is temporary. However, whenever the pain becomes unbearable, i can't help it but to go for another session rather than taking too much painkillers (Ultracet, Tramadol) which will damage my liver.
Its all up to you if your finances allow, to find temporary relief and control. Try going once a week may be kinder to my wallet though, will still try not to go.
Do some stretching exercise and walking helps a lot instead of lying down and sitting too much.
