I have previously done 3 SI with someone else watching me for moral support. This morning I have done my fist SI without anyone else around. Had to sit a few minutes to build up courage and stupidly cut my finger breaking the ampoule which didn't help.
I don't know what has happened this time as my thigh is a little tender, feels slightly firm and aches in a 2" radius of the injection site. I used a 1.25 " long needle, 23g but didn't insert the whole length, probably only just over 0.75" as the last time I injected I inserted the full length of the needle and the injection hurt more at the time than before but not afterwards.
Did I make the mistake of not using the full needle length. I wouldn't describe myself as slim but not overweight. BM1 23.4 so at the upper end of healthy.
Sorry for the question but I am learning about SI and have no one around for even moral assurance.
