Thanks fot the query , it is also know as Thallium stress test
, they want to check out that your heart muscles are alright and secondlty under stress the blood vessels are supply the need of your heart muscles. IT is a simple test you need not to worry at all.
I will agree with rest of my colleages that this can be due to cervical spondylitis
, resulting in pressure of nerves and you get these pain too an MRI
is done or a simple xray of cervical spine
can make the diagnosis.
IT can also be due to osteochonritis and the symptoms mimic a heart problem, i too get this thing at times.
Anyway get a clean bill of any cardiac problem , the rest is a piece of cake.
In my opinion you are facing some sort of tension/stress after thoroughly going though your case history.
your bp is excellent quit stimulants and caeffinated drinks OK.
