Had a tooth abcess going on a month; was given erythromycin weeks ago but made my heart go nuts so told to stop taking them. Abcess got worse this week and felt poorly too so advices to start again. 2 days in and hideous nausea and stomach cramps been told to stop taking them again. When will the nausea and pain stop. Last dose was early aft due another now which obvs won't be taking. But feel worse than ever. Home alone with DS 2 as husband working away. Struggling badly need to know some light soon
