Terrible Pain

The pain in my legs and feet have been so bad yesterday and today. It's almost unbearable! I had physical therapy yesterday and it flared up the pain. I just don't know what to do. I don't feel like my doctors are listening to me. I feel like throwing in the towel! Just giving up but I don't know what that means either! I am just so tired of this terrible pain all the time day in and day out! Oh God hear my cry!!!
