I've been on Excedrin migraine for over 10 yrs and I take anywhere from 12- 16 a day. I've noticed right upper side pain and cramping when I laugh. It seems swollen it also hurts after eating. My boyfriend thinks I'm crazy when I tell him this. Would I be worried?? Also it is uncomfortable to sleep on my left side because it feels swollen so I sleep on my right side to put pressure on it. Also excessive heartburn... Need answers plz.
