I hit my head and got a severe concussion in May 2014. I could not drive for 2 weeks because of the vertigo and I went to physical therapy for 3 months because of the vertigo. Recently my vertigo seems to be coming back and my appetite has increased since May. I have gained about 20 pounds since May. My activity level has slowed down but I seem to be unable to control my appetite. I also have issues with memory and concentration. I am 49 year old women 5 9 and weight 183
