Tightness in throat symptoms and conditions

I had stomach pain, pain in chest, tightness in throat, then horrible rash. After a month on prednisone I started breaking out as I decreased the dosage. I told my doctor I thought it was the Lisinopril and I stopped taking it. I'm feeling better now after being off of it for a week, but still not 100% o.k. I talked to the pharmacist and she said, "You must be allergic to sulfa". I am very allergic to it and have always listed this on the forms in the doctors' offices. Apparently there is some relation between lisinopril and sulfa.

I've been taking levoxyl for 8 years now with mostly good success. My endo doctor recently upped my dose due to lab results (I think the test results were bad). Now I feel horrible. Headache, dizzy/lightheaded, blood pressure increased, tightness in throat, and muscle cramping. I've been to many specialists concerning the dizziness - everyone says I'm OK; cardiologist, ENT, and neurologist. The symptoms started a few weeks after the dose increase, and have worsened in the last week or two (about 2.5 months out).

Took Doxy in Feb 02 for inflammatory infection (50mg 3 times daily for 2 weeks). Suffered muscle spasms, palpitations, dizzyness, severe weight loss and tightness in throat after 2 week dose. However, similar but not so frequent symptoms over 2 years later still persist including general aches and pains, tinnitus, itching and many more strange and not-so-wonderful feelings. Have been told these symptoms are due to anxiety / stress but I'm not convinced. A colleague has recently experienced similar symptoms after being prescribed doxy for an infection. He still suffers the same symtoms some 4-months after stopping doxy. One to avoid if possible I feel.

Anaphylactic reaction, blood pressure dropped to 70/40, flushing, generalized hives/angioedema, tightness in throat, diaphoresis, palpitations, and lightheadedness(even near syncope) and hypotension. Alterations in the kinin metabolism pathway due to the ace inhibitor
