All day my left ear wasn t hearing properly and then suddenly this evening loud ringing started in it. If I cup my hand over it, no change but if I poke finger in, it s very loud. BP 139/76 but the noise isn t pulsating. A week ago I ended 7 day course of clindamycin and a few days ago I started taking Omega3, acidolphilus, CoQ10 and a multi-vitamin and I ve been taking metoprolol 100mg/day for 18 months. Could the clindamycin ago effect just of my ears a week later?
