Hi
Thanks for writing in.
Patches of hot sensation on leg, face or other parts might be indicative of sensory neuropathy, multiple sclerosis, peripheral neuropathies, nerve entrapment, diabetes, vitamin B12 deficiency and several other causes. Do you have any other associated symptoms like visual disturbances, balance problem or others? You should consult a neurologist for a complete examination. An MRI may be required to diagnose the condition.
Do write in if you need more information.
Take care
Yes it is close to somthing which i had for 4 decades.. I am 78.I used feel hot in my soles for few seconds anytime anyday in summer and in winter I used to feel cool/heae sensation for few seconds. I maust have talked many doctors(I was medical representative) and none thought it immportant. Now I am 78.I havesensation of tight feet without any problem in moving.Pathology is not known.All test(including neuropathic) are negative.You will find number of postings under "numbness" All complaing about unexplainable sensations without any cure.Sombody did say that chiroprocor helped and the patient get cured. We dont have qualifed chiroproctor in India atleast in the town i reside.I am trying to find sombody doing chiropractice.
