<s>[INST] my son 19 yrs. lives at home, was shot in head front lobe bullet exited right out the other side august this year.  now left side of his head around the temple has started to pulsate with a sunk in apperance.  now hes complaining of eletrical shocks shooting through his abdomen and they become quite painful at times they radiate to his hands and arms. carol [/INST] Hi. Shoch like pains in the abdomen of your son is obviously due to the trauma to the brain in bullet shot. IT will show its effects all the time in life. The radiating pains to the arms and hands may have the same reason. I would advise you to consult a Neurosurgeon, get MRI of brain, and start treatment for the pains. Also go for check-up f the abdomen to rule out any actual disease in the abdomen causing the pains. </s>
