How about your BUTT? I get my fiance to do that one... it's a bit challenging. I hate the thighs but I do them anyway when I'm feeling brave. I guess I'm greatful for my nice jiggly belly as it's usually pain free.. lol.
I think the idea is to inject into fatty tissue, and AVOID any areas where you might irritate the injection site. Like, avoid areas where clothing may rub (waistband, pantylines, sleeves). Avoid areas where you'd be pressing down when you sit. Avoid areas that you've injected recently, which might be irritated or swollen. If the injection sites get irritated, they can get infected, and then you've got a much more serious medical condition on your hands.
I'd probably avoid the area of my butt where I sit...but that still allows lots of other injection sites all around my lower torso.
I had the same problem when I was injecting. I even talked to my doctors about it. They told me that guys especially, have a problem with upper arms and thighs. Some even with butts (whoops can I say that here)
Anyway, what they told me was two things. One, don't inject there. Rotate the stomach and butt and if absolutely necessary the arm. But Thighs are horrible. Two, if you use an autoinjector set it for the smallest needle insertion. You will probably get more red marks, but it does work on some. And.....they also said that you can go in at a 45 degree angle in some spots.
When I asked them about the instructions and what the nurses said etc....they told me that they give you a general outline for MOST people. They continued, that diabetics have the same problems and have had to vary and adapt.
So for what it is worth......A lot of macho guys, with six packs and huge guns, tight butts and hard thighs (cough cough) have this problem. (And so do skinny guys)
Contact your Doc, and talk to them about it. Nurses deal with this all the time and have lots of tricks it seems.
I rotate all 7 areas. I use the AJ. My hubby does the rear/hips, and both arms. If I am ever alone. I will compress the AJ closed (being careful of course!) and I will take packing tape and tape it closed so it is activated. I then hit the button with one hand and it's done. I've done this many times but I always make sure the tape has a good hold on it before I attempt the injection.
