I went to my GP who then prescribed me
clindamycin on top of the erythromycin and codeine
for pain. When I was only taking erythromycin, my stomach was hardly upset, if at all. Now that I'm taking the clindamycin, my stomach is killing me. There's no diarrhea as of yet, but the amount of stomach cramping I have is insane. It's not abdominal pain, but stomach pain, just below my chest.
