I am suffering from chronic hip pain.

I am suffering from hip pain from last 2 years.. i have tried different physio therapy options but none gave relief. The pain starts from lower back and it hurts my feet too. Sciatica exercises won't give me relief. I cannot stand or sit for more than 15 min. Sitting leaves me poking hip pain in both sides. When i stand the whole leg hurts. From last month my left foot is hurting bad and sometimes it feels like severe pulling in my foot and something might break. In addition to this i have fibromyalgia symptoms. I had positive reaponse for duloxiten and pregabalin. Also i have straightened curvature of cervical spine. I would like suggestions which speciality i need to consult regarding my back and hip issues. I am looking forward for pregnancy which might be difficult with the hip pain.
