Most of the day , my right legs feels thicker.It feels wierd while walking for 20 mins. Besides my thigh ,I feel my butt is bigger and hip too. When I sleep during nights upside down, I can feel something in my right lower abdomen as if it's touching mattress. Also I feel like a lot of gas and stools getting stuck there. Please help , I wanna walk normally. Also I found out tht my left leg is 1 inch smaller than right, I didn't know this until before 6 months , not sure why i am seeing tht all of a sudden. I had an accident before 2 years, but no fractures as such happened at all. I had brain,spine,blood tests done , all are normal except b12 and D which I am taking suppliments for. I am afraid if something bad happens to me.
