Few days i'm getting a heat sensation in my leg, between my knee and the foot, it lasts 5 seconds, 5-10 times a day, not warm at touch. what is it?

Nerve root: You have previous issues with weight and back pain, which are a result of stress to the nerve roots of your spine. The only way to relieve symptoms in a longer-lasting and meaningful way is to think about dieting and weight reduction, to remove the pulling force your belly has on your lower spine

Possible neuropathy: If you are overweight, there is a chance you could be developing diabetes and diabetic neuropathy as a complication. Also, spinal compression on a nerve can lead to neuropathy as well. A burning sensation on the legs, followed by numbness, is the usual course for neuropathy. Get checked by a doctor; consider an EMG/ NCV test for diagnosis. Good luck, thanks for asking HealthTap.
