I have been diagnosed as having a center disc herniation. I have an appt. with a neurosurgeon in two weeks. I ve have numbness in my hip, left leg and foot. Well today my left calf and foot are cold. I have a heating pad on it and it s still cold. Is this a symptom of a center herniated disc?

### output:

Hello, Sorry to hear about the disc injury you are having. Coming to the disc injury, any disc injury is not Mandatory that it will lead to the motor, sensory, motor sensory both or no symptoms. The symptoms are totally individual based. In your case, the nerve is getting pinched by the disc prolapse which will be a small fragment troubling the nerve on its nerve root where it is coming out of the spinal cord. Nerve has got two major functions - one is motor and other is sensory. The motor includes movement and sensory included the pain, temperature, numbness, tingling etc. In your case it is sensory and by this, the motor functions are reduced.  As you have tried to put hot water bag over the calf which was cold, I would recommend trying keeping it over the lower back, as that is where the nerve root is. Once the nerve root gets the warmth the nerve supplying the muscles will get warm sensation back. Also, with this, the pain will come down. Now coming to the therapy part, if you have unbearable pain then medication might be looked for. But most cases are ceased from medication after 7 days. I will recommend you to first try out the McKenzie maneuver of lying on the stomach and making an extension of the spine with the help of the upper limb. You can check this out online. As this maneuver is kind of at its best to centralize the pain only in the back region. Once you get the pain centralized in the lower back you can use hot water bag over it to provide the soothing effect. Once there is centralization and soothing of pain you can start slowly the core stability exercise and also the lower limb strengthening while lying on the mat. In my clinical practice of 12 years, a maximum number of cases have responded well with the McKenzie maneuver and exercises. You can take the help of a physical therapist if you wish to. You should do well in 3-4 weeks if time. Post which you can continue exercises like 3-5 days a week. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.
