I am having excruciating pain. I have had pain for quite sometime, but, it has worsened in the past month. I am scheduled for nerve blocks next week. Presently, I feel as though something is ripping me apart, as though a knife is being jabbed into the right of my lower back, am having electric shock sensations going down the back of my right leg and then down into the calf. I, as well, have had to vomit. I cannot hold food down. I having PROFUSE stinging and "pins and needle" sensations in my abdomen, right buttock, right hip. I don't know what ER can do for me. I have been there many times and always am given a shot of Dilaudid (3mgs). It only lasts about 45 minutes. What I am experiencing now is unbearable. I am not a crier or screamer. If I were, I'd be sobbing and screaming at the top of my lungs. What do you suggest that I do?
