I am a epiteptic patient for last 15years. And I am taking medicine for 15yrs. Last attack was on 9yrs back. My age is 33. I used to masturbate alot in childhood (2-3 times A week). Now I controled it a lot. Now I feel a sensation on my knees  and shoulders joints, as if I seems to fell down. If I climb a staircase i feel the same, if I walk a long walk i feel the same, even if I have a large volume of work sometimes I feel the tiltation or sensation. When I stay alone the feelings comes very strongly. And I think that I will fell down. Please help what will i do? Please suggest I am very nervous now.
