Hi! I am a 46 yrs old woman. I am allergic to all NSAID. I get swelling in my eyes and in my nasal tract and mouth and my air passages becom constricted. I cannot breathe. This happened about 20 years ago. So I started taking a paracetamol with an avil for fever and headaches etc. it worked well for a couple of years. Then I got allergy to that also even though I had taken avil. Then I got introduced to Tylenol . It worked very well and I could take it without and avil or Allegra . But about a month ago, I developed an allergy to that also. So now I am stuck. I don t know what I should take when I get a headache or fever. I take tramadol.....but it doesn t really help headaches or fever. Please help. Thank you.
