Hi I know what you mean to be claustrophobic ,, I am not extremely bad but just don't like idea of tight place,, and the feeling of not being able to move or get out,, even though they will pull you out if you really need it,, they are watching and listening to you; however, it really is just a mind over matter situation ,,, you HAVE to make yourself believe you are alright.... Because you really are!
I take a different approach though when approaching room... I Purposely do not look at machine or anything in room as I go in for test,,,I do not want to see what I am going into ,,I lay down and close my eyes,, they have in the past even given me a cloth / washcloth type to put over me eyes to help keep them closed,, I NEVER open my eyes once in machine ,,,and I sing songs to "entertain" myself,,I have found out that there are different size "tubes" on different machines ,,, the first one I was in was very tight,,, very stressful!! Thankfully ,, my annual MRI, which is being done on the 25th,, is in a larger tube at the hospital ,, but bottom line is you really have to work hard to "convince " yourself that you ARE going to be ok,,, really!!!! They wouldn't put you in there if it was going to hurt you in any way or if you weren't going to fit
,,,I know it's hard,, and harder for some of us than others,,
Good luck,, to both of us,, as I approach my annual one too,,,WE CAN DO THIS,,,
,,, I will pray for you, if you will pray and think of me during yours!! And take whatever your Dr gives you or suggests may help you,, I too have taken Valium in the past, but only the 10 mg to help relax me,,,,it helped,,but I have had about a dozen of them since 2008 diagnosis ,,but still not very "enjoyable "!!!
Good luck,, Jane
