My eight year old is allergic to amoxicillin, zithromax, clindamycin, and cefzil. We have seen an allergist, and he said there are no tests for antibiotics and that "we have a problem." Can someone please guide me in what to do next? My doctor was hoping the allergist would help guide us for future treatments. I am fearful for any infection like strep throat, ear or skin infections, we have run out of options.
