Hijamah in Salalah

I've always believed in scientific evidence and thus scientifically proven medicine.Alternative medicine is perhaps one of the things that I somehow doubt. Acupuncture (among other alternative practices) is one of the things that I highly doubt. May be because of its chinese origin. However recemtly I started thinking of trying Hijamah. This wikipedia article is perhaps good for those who don't know this practice. 

I heard there is a place where it can be performed here in Salalah at Amer Al Maashani building that is opposite Alzawiyah mosque. I'm not sure if there is another place where I can do it, or how effective this practice is. All I know is that i'm fed up of my frequent headaches...
