I have severe gingivitis, am now taking Clindamycin (Amoxicillian didn t work) and 7.5/325 Norco. After leaving the ER last night (severe pain), and a shot of Clindamycin and Torradol, I began having chest pain. I ve taken 3 oral doses of the Clindamycin, and 4 doses of Norco today, and the chest pain has gotten worse. Left chest, from my armpit to breastbone. My blood pressure is also elevated, and even with extra bp meds, hasn t returned to normal. Could this medication be causing the chest pain? Or the infection?
