I am sorry to hear about your medical problems. Entirely based on the symptoms you describe it looks like sciatica, where the sacral nerve of sciatic nerve is either irritated or pressed upon. It generally happens when you bend or lift things the wrong way or sit for long in a particular position. However what can be serious is a slip disc or a bulging disc as the cause of this pain. The pain can also be due to irritation of the sciatic nerve from infections, injury, pressure from an adjacent bone, tumors etc.
A neurologist is the specialist you should approach. Maybe your PCP can help get an early appointment. A MRI will be required to access the situation. Some patients benefit by conservative treatment (pain killers, muscle relaxants and rest), others need varying degree of traction and few need surgery. Physiotherapy is definitely required. Refrain from lifting weights, bending and straightening with a jerk, jerky rides on roads etc. Take care!

Hi.. thanks for the reply..
Just wanted to update few things on this...
I've been doing stretchings everyday and now the pain has come down to a great extent.
I dont get a painful sensation whenever i stand up from a sitting posture.
Plus there is no pain in lower back now.
I am having a mild pain only in the hip area and that too when I sit on chair for about an hour or wake up in morning. It feels like my hip has been squeezed tightly.
This feeling goes if I take a walk or stretch for few minutes.
Please tell me its not a slip disc or bulging disc...
