Welcome @mjthornton78. It’s pretty normal to be scared when you’ve gotten a new diagnosis, especially if you don’t know much about. It leaves you feeling very lonely. So I’m glad you joined Connect. There are a number of members who also have Factor v Leiden which is a blood disorder which can cause abnormal clotting.

I’m not sure what’s been explained to you so I’m putting a few links with information about Factor V Leinden for you to read.

If you don’t mind sharing a little more of your story, how was your diagnosis discovered? Were you experiencing blood clots? Are you currently taking any treatments to help prevent abnormal clotting?
