What Causes Numbness Or Burning Sensation In Right Front Thigh?

Hi Doc, I suffered since one year from numbness or electrical shock or burning from my right front thigh only. I visited the nerve doc and informed me that I had Meralgia and I should not wear tight clothes, belt etc.. And not to stay on chair for long time, they did examination to my nerve function on the same area and found OK!!! Finally, Doc prescribed for me nueriboin coated tablets to use once daily. I remember that I use it for few weeks and stopped the dosage. The pain still persist but intermittently. Do you suggest more effluent treatment as this symptoms is nuisance to me. Thanks Doc.
