Hi
I've had 4 cycles: 3 Long and 1 short protocol.
I've had many injections over the cycles, and the injection site does become sore. You inevitability go into the same injection site more than once without knowing, so that can start to cause some stomach tenderness over time.
Tenderness/soreness is ok, but the injections shouldn't be causing you any pain.
I used to grab as big a handful of my stomach as I could, and hold firmly- that would take the edge off a bit.
Try to relax and do the injections as swiftly as safely possible.
In terms of my ovaries, i did feel uncomfortable and heavy but that was only at the stimulation phase, but again no pain.
Perhaps you should mention to your hosiptal/ clinic at your next appointment.
I don't really have any other advice. Hopefully someone else will join the thread and give some tips to alleviate the soreness. I'm starting cycle 5 next year, so I'd be glad for a tip myself!! X
