I've had too many surgeries, but never feared them. They were always performed at a good hospital by excellent surgeons.
In 1978, I had an emergency appendectomy on a Friday evening and was back at work Monday morning. Getting out of the hospital that quickly required hard work and accepting a certain amount of pain, such as by getting out of bed as quickly as possible and forcing myself to walk up and down the hospital halls and going up and down the stairs, in spite of the discomfort.
In 2006 I had a compound fracture of my right leg. The surgery, which included putting a titanium rod and five screws into the leg, was performed on a Thursday evening and by Friday morning, I was going around the hospital on crutches. I was told that most patients don't get out of bed quite so quickly. Of course I couldn't use the leg for a while, but when healing had sufficiently progressed, in spite of the considerable discomfort I pushed myself to recover as quickly as possible.
Surgery is nothing to fear if it is done by a highly qualified surgeon in a good hospital and if the procedure required is routine, uncomplicated, and well-understood. Speed of recovery depends on the ability to tolerate a certain amount of discomfort and push yourself within reasonable limits. Patients who say, "But it hurts!" and are slow to get out of bed recover more slowly.
