Joined in Feb this year - this forum has members from years studying and taking aspirin. Have you? NSAIDs other than Aspirin do cause all sorts of problems. Some people do have an allergy to salicylic acid - but very few - most do well on aspirin.Hold off on the visions of aspirin panacea. It seems unlikely that everyone would benefit from ASA and none would suffer adversely. Knowing who is the essential missing information. As should have been better studied also with clotshots.
