Sulfamethoxazole and definitly

I was given sulfameth/trimetoprim for and ear infection and the first dose made my tongue feel like it was swelling up,then I noticed my hands and feet were very cold,and I felt light headed,dizzy and my throat felt like it was swelling up or like i had a lump in my throat .By the time i got to my fifth pill i could not sleep,i could feel my heart beating in my back and when i took a sip of water it felt just like my thorat had a massive lumpin it. At that point i called my doctor and they said that i definitly had an allergic reation to the medicine.Now the doctor is going to switch my medicine but i am still feeling bad and am afraid to trust them with my health.These same doctors used to treat my 19 year old son for contipation,anxiety and as they put it "girlfriend trouble" which was actually insomnia but he ended up being diagnosed with stage four colon cancer and passed away fourteen months later.stay away from this medicine and always ask questions and keep a log of your doctors and treatments.
