I have recently (past 7 months) been having headaches, stomach pain, and pain along my shunt
tubing but no redness, swelling, or sickness. I have had multiple X rays and cat scans, but my neurosurgeon seems confident that nothing is wrong. Recently the site of my stomach incision has been tender and a bit sore, not red or swollen. Is it normal for scar tissue to feel sore / tender at times?
