What causes warm sensation on leg?
Patient: hello doctor. i have a warm sensation every now and again on the outside of my right leg it goes away after a few seconds i had this about 2 years ago on my right leg . i do have a sciatica problem and thats causes my leg and back to ache. not sure if it is connected. hope you can help me on this. thank you sue. Doctor: Hi,  Yes this is connected to sciatica. As the nerve carries two function - sensory and motor. When motor is involved there is weakness. When sensory is involved you will have touch, temperature, pain etc as symptoms.  The change in feeling of the hot and cold sensation is carried by nerve and so as you mentioned you had sciatica than it is one of the reason. Kindly do regular exercise which you may have been doing in past for your sciatica. Symptoms should subside sooner.  Hope I have answered your query. Let me know if I can assist you further.
