Partial numbness below right knee.

Hello doctor, I'm 33 years, weight 88 kg, height 5ft 7inch with no comorbodities except grade II fatty liver. For last few days I was feeling partial numbness below an inch of my left knee upto about six inches down the length. I feel the numb sensation when I run my fingers across the area but I can feel sensation when I pinch the area. I generally used to sit on bed crossed legs for almost 5-6 hours though with break every day to work in laptop. I was suggested to have Felicita OD once a day for 10 days and to avoid crossed leg sitting by a neurologist which I followed strictly but felt no improvement. I also tried using hot water bag in the area. I'll be highly obliged if anyone of you help me to resolve the issue. Regards and gratitude.
