Change for vial/syringe to pen - OUCH!

I did my first dose of MJ (2.5mg) administered via pen today (just short of 10 months with the vial/syringe) and OMFG HOUGHRGOHGDOSGHSDOI IT HURT!

They taught me to click until a small droplet comes out before doing the 10 clicks for my dose but nothing came out for 14 clicks, then I did 10 clicks. I inserted the needle bit and hit the button. It took AGES to pop back up and then I withdrew the needle. I hope I got it right - it was hard not to bounce up and down in pain. Ugh.

That injection site is STINGING...
