I was Hurting for about 5days but continued to be tender for about 12 days with it feeling a little better each day. I am now 2wks and 4days out and have no tenderness. I sleep on my stomach so I really felt my tenderness. My doctor told me I healed fast so I may not be tipical. I am also a nurse. Im suprised that you got approval at 170s. I was 247 at 5'2". I lost 13 lbs and then gained 2 back. Too many cal. I hate diet liqs. Oh well I hope this helps. Hang in there. It really does get better. Probly not before you feel frustrated, but that too will pass.
