Hi Perissa,
I don't know anyone who hasn't had the heparin injections, but maybe I've missed someone!
I am extremely needle phobic and couldn't do mine. It was arranged that hubby would do them and they showed him how in the hospital. But when it came to it, I couldn't let him (well he's not a nurse!) so i ended up going to our local walk in centre once a day for the first few and to my gp's nurse for the rest. They were fine about it, and it made it MUCH easier for me to cope. It's only one a day for 5 days after discharge and it really is in your best interest to have them.
If you do plan on getting a nurse to do them make sure you have something in writing from the hospital to say you are to have them etc.
