Blood tests, scans and anxiety....

Last friday I had my 3 monthly CT scan I'm waiting for results and as is the normal for my hospital it could be some time anything up to 8 weeks (I'm not kidding!!!!). On Tuesday I had my 3 weekly Herceptin shot in the leg which has left a big black bruise and tomorrow I go in for a blood test to verify the status of my thyroid and also to check my blood sugar levels straight after that I go onto the hospital for a heart scan (Herceptin affects your heart) so its been a week of scans, tests and anxiety. I always feel anxious waiting for results which is understandable but its also the anticipation of having to have a cannula put into one of my poor collapsed veins it stress me out no end, they never get it right or listen to me when I tell them don't try that hand etc so subsequently they try 3 times and then hand over to a doctor who invariably looks about 10!! who tells me not to worry it wont hurt and he'll/she'll find one and hey presto it always does bloody well hurt and they have a good poke around to try and find it. WHY DON'T THEY JUST USE MY FOOT urghhhhhhh...... its so fucking annoying.
