hurting back

My back is killing me for the past few days, I don't know what causes this. But my mom told me it could have been from my long hours of computer time, without the proper posture things can get really bad specially for one's body shape. Thinking of getting a back brace, or shall I seek the help of professional first before getting myself one. Let's see, will try to have this back ache be check next week by our family doctor, and maybe he'll refer me to a specialist. Been trying to drink bone supplements too wishing things can get better! So there, might just browse sites that sells out medical stuff like Allegro eCatalog. I heard a lot of good things about this site, so I bet their prices are well marked too. :D
