I had that experience before when I was 16 yrs old I guessed it was in my right hip and affect my walking ability cause I felt there some vein in there like stock, It last a bit longer like a month not too painful but you can felt it and I am not comfortable until I slowly saw my standing posture curve or deform a bit noticeably but thank God I remembered I just keep on stretching side by side and while I am lying in bed just raise my right leg up and down and in circular motion and eventually its gone. This not a therapy advice just telling my experience. Thank you for sharing this @coraljessalyn it's a good information.
