ABWG,
I am sorry you are having this worry currently. I know how it is to get focused on something and not be able to get it out of your head.
However, I agree with Lendi. This is probably something so rare...as to really be a non-issue. The pharmaceutical companies do have to do a CYA in reporting these extremely unlikely s/e's...that seriously may have no risk to the average consumer.
I have done a lot of research, and read A LOT of posts here over the years (look at my own post number and multiply that by a few thousand, lol!) and I have never heard of this particular complication.
I second the idea of talking to your doctor or pharmacist for peace of mind...and hope that you can put your time and focus on learning coping skills, rather than Google searching any unlikely issues with your Rx.
Peace and progress!
S.C.
