Comparing Dipyridamole vs Lexiscan

For Diagnosis and Investigation I originally went to hospital with chest pain radiating to my left arm in the middle of the night. Being a previous MI patient they did continuous blood work until noon the next day and then did the lexiscan. This was the second lexiscan I have had and by golly, IT was UNCOMFORTABLE! I nearly ripped the technicians leg off because I felt my chest tighten down so darned hard. Well, the test went well and I went home that eve. Two days later I began itching all over my body, then broke out in hives. That was on Oct 25th, it is now Mar 3rd and the dermatologist has tried everything in the book to stop the hives, to no avail! I have walked the floor all night because it itches much more when you are at rest. I am 69 years old and have never had any sort of skin problems, but this, this is driving me insane and the only thing that precipitated this horrible case was the lexiscan! I don't know who to report this to so maybe someone can direct me. Thank you.

For Diagnosis and Investigation I had this test today. I did feel somewhat dizzy and flushed but for only a couple of seconds, I did get a headache that did not go away so they gave me the antidote and it went away almost right away. It was not as bad as I had expected. The only thing I am wondering about is later in the day I became very nauseated not sure if this was from the medicine.
