Hi and welcome.
Sorry about the pins and needles. It could be that whatever issue is causing that can be causing the high blood sugars. It doesn't have to be, it's just a suggestion.
Regarding the pump... I was on injections for 12 years (approx) before I was able to get the pump. I fought tooth and nail to get it and can certainly say it has made my life much easier!!! I LOVE the pump in comparison to injections!
My pump is old, (I'm due for a new one) so it's not particularly comfortable as I've long lost the clip to attach it to my waist band. I love putting it in my jeans pocket though - it's comfy all right there. I don't have experience with the omnipod, but I do understand there's no wiring with that.
I find it easy to use and certainly less stressful than injections. It takes a little to get used to it, but after that - it's just part of my life, part of me, and I'm grateful to have it on me all the time so I can bolus any time, any place without much hassle.
Regarding morning highs - because you have the option of setting your basal rates at an hourly rate, you can make your basal rates as high as you need them, for the times you need it. Many people have higher rates in the early morning. It's not just a flat rate to last 12 hours so you have the flexibility to adjust as your body needs.
With regard to HbA1c - many people say it helps them. I've struggled to get my diabetes in control. I've had issues with taking my insulin too, so for me, personally, the pump offers me flexibility and simplicity but it didn't cure my emotional problems. I'm working on lowering my A1c now, after 8 years of pumping.
I still dislike inserting my site, still get nervous each time, but it hurts way less than when I was on multiple injections and had to take insulin so many times each day.
With regard to your job - either you can place it in a place that you cover up, so nobody sees it. Or, you can joke about it. I wear the Dexcom CGM on my arm and when people ask what it is, I tell them it's my experimental wifi hotspot using my body's heat for energy. You may be surprised at how many people have believed me. I have compiled responses and will post it on my blog.
Is it worth it? For me, it sure is. I'm one happy pumper.
But everyone is different.
