Sciatic Nerve burning and numbness in right upper thigh.

A month ago I was sitting on the floor pricing garage sale items and moving boxes nothing heavy, I've always had a little burning in my right hip and felt it clear to my heal.. The next day my right hip hurt so bad it was going down my right leg.. My dad gave me some pain killers and muscle relaxers because I could not sleep, over a week of this went by and then my top right thigh went numb like it is asleep but it will not go away, that went for almost a week , then I decided to go to a chiropractor, I went 3 times he said it was my sciatic nerve and it takes time for them to heal..My hip fells better it is still burning but bearable my thigh is still numb and burning and I can't lay on my right side very long it is real tender.. How long do you think this is going to last? I've never had this last this long and never had the numbness.
