This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Do you have any other pre existing condition like Diabetes?
This type of sensation is due to the sensory nerve perception disorder.
The sensations are carried by the nerves to the brain.
Any abnormal conduction will cause these sensations.
This can occur normally as well in case of emotional or physical stress.
Also pleasurable activities sometimes can stimulate the wrong part of the brain.
Persistently abnormal sensation can be due to the underlying causes like diabetes, thyroid disorder, vitamin B12 deficiency, neurological conditions.
But these are less likely if you do not have any other problem or these sensations are only temporary lasting.
It was my pleasure to help you today.
