Sub-Q Injection Woes

Today is treatment day.
Slowly and separately, I did both my Berinert and Methotrexate injections. I find that when I get all of my supplies out for Berinert, that is when I remember my MTX the most, so instead of putting it all away and then subsequently forgetting entirely to do my MTX that week, doing it on the same day seems to work best.

I mean, today was already basically a write-off, so doing both injections on an already sleep-away day is more effective.

Lately I have been focusing on eating better and exercising more, and along with less swelling, this means that I am slowly getting into better shape. THIS I am thrilled about. Spring has begun today and we have a wedding coming up in 6 months, so keeping myself in shape is a relatively high priority.
There is only one problem.
Sub-q injections are injected directly under the skin and into the fat layer between the skin and muscle. This means that there has to be a large enough layer of fat for these injections. Now if I was only doing one sub-q injection, it wouldn't be as big of a deal, but I do these injections three times a week with an extra one once a month. My thighs and upper arms are primarily muscle, so my abdomen is where I inject, and now that I am losing stomach fat (on purpose), these injections are becoming more painful. These injections have to be done in cycling spots each time, and I am supposed to avoid injecting near scars, bruising, and other injections.
Today was even an 'oops' moment. The second I inserted the needle, my abdominal muscle (on the right side) contracted/twitched, and the injection was far more painful than usual. It means that the fat layer in the area I chose today was not large enough.

Usually I feel like this is good news. It gives me an excuse to always have a little extra chunk around my tummy. I can be a little liberal with my eating - all because I have to have a workable fat layer available three times a week. Right now, however, reducing that amount of fat is a goodnews/badnews scenario.

No pain no gain though right??
