If you are a doctor, please answer the medical questions based on the patient's description.

### input:
I have had a CT scan done abt 15 yrs ago which said that - Diffuse annular disc bulge with a small right paracentral herniation possibly compressing the right traversing nerve root at L5-S1 . Today am 39, weigh abt 75 kilos and have a pain radiating into my right leg on and off, pain in the right foot almost constant - specially in the heel and the area around and below the last 2 toes. On days of exertion and PMS, the right leg feels heavy with slight stiffness and swelling from the knees and below. Wearing a pair of socks, putting a lot of weight with 2-3 woolen blankets gives some relief. Exposure to cold weather brings back the pain. My physician recently examined me and told this is a trouble with the sciatic nerve. He has advised not to do any forward bending exercises. Can someone explain what the condition is and any particular specialist I need to consult.

### output:

Hello, You may be suffering from a slipped disc in your lower spine with pinched nerve. To put in simpler terms, the lower limbs receive nerve inputs from your spine. So whenever you have slipped disc, the disc comes and compresses your nerve (pinched nerve) which causes your whole limb to feel numb and weak. In your case the CT scan done previously has diagnosed your condition at that time, but the best thing is to get an MRI scan done of your spine which will tell you in detail about the spine and the nerves. After doing the MRI scan your orthopedic surgeon or spine specialist will be in a position to guide you further. In the meantime you follow the advice given by your doctor (not to bend forward and lift weight). Hope I have answered your query. Let me know if I can assist you further.
