Won't go away.

So this is my 3rd week walking. We started of slow and are working on go farther out each week but I think I'm stuck. I do well walking to the point but on my way back I start limping more and it hurts more to walk. After the walk I even noticed that the lump on my left arm was swollen again. I thought it wouldn't come back but it still does. I was hoping everything would go back to normal after the surgery. After walking I must remain intermittently active otherwise I won't be able to move with all the pain. My neck still hurts when I turn from side to side and and the insicion still itches from time to time. The kids have also noticed I walk a little better but I'm no where close to walking as fast as I used to. I hate thinking this is how it's going to be from now on but sometimes I don't see the light at the end of my tunnel.
