Feeling crawling sensation on the same sport everytime this happens and some other times pimples will grow there and disappear again it been more than 10 years now ?

Sensory Symptoms : This is a long time to have intermittent sensory symptoms. What does your GP physician think about this? There is a wide "differential diagnoses" for this, meaning it could be lots of different things, neurologic and otherwise. I would get a referral to be seen by an experienced neurologist.
