I've had PA for about 8-9 years now and I'm perfecly comfortable with the situation. I have the injections every 12 weeks and I never feel the effects running out, which is great.
But what is really bothering me is WHY I have to go back to the GP surgery every 12 weeks to have this injection? After almost a decade of them, I could do it myself blindfolded, without wasting NHS resources and without unnecessary inconvenience in my own life. So why can't I do it myself??
