I am allergic to aspirin (anaphylactic shock). I am also allergic to grasses, dust mites, mold, pollen, etc. Shots sometime cause systemic reactions, so Dr. recommends drops under tongue. HOWEVER, he also recommends aspirin desensitivity process, which would allow me to take aspirin daily to help prevent heart disease/cancer. I am 70, have generally good health with no heart attacks in history. I have received every kind of response to whether or not I should do this, from good doctors. What is the consensus?
