I wish that I had a nice, satisfying solution to this (that didn't involve chewing on healthcare professionals), but....

You wrote earlier that you were able to take meds before - are the meds that you're now allergic to, the same type of meds & are you taking different combinations/dosages? Allergies can come & go - sometimes it's tolerances within the body, other times, it's more environmental (diet/location/stress/nutritional content of consumed healthcare professionals).

What changed between then & now? (Might be impossible to answer, I know...).
