wellmeaning busybody…
This goes back to a known concept…
While you’re not supposed to shop around for kula’s,
it IS appropriate to talk to a rav who CAN relate to YOUR situation.
L’moshul – the case you mentioned. A rav who never, ever had a problem with allergies, is much more likely to be machmir about taking allergy meds than a rav who has suffered with allergy symptoms.
