I have extreme lower debilitating abdominal pain on the right, middle and left side, burning, throbbing leg pain in calves and thighs and I m nauseous. I had an appendectomy on July 10 and pneumonia. I am 44 years old as of July 30th. The pain is 10 out of 10. I also have chronic lower back pain-several fusions, internal spinal stimulator, and internal pain pump. The pain is unbearable.
