To locate the best place for injection in the upper arm, start with a completely exposed upper arm. You will give the shot in the center of an upside down triangle. Feel for the bone that goes across the top of the upper arm. This bone is called the acromion process. The bottom of the bone forms the base of the triangle. The point of the triangle is directly below the middle of the base at the level of the armpit. The correct area to give a shot is in the center of the triangle, 1 to 2 inches ( to 5 cm) below the bottom of the acromion process.
Today, however, I was injecting particularly far into the back of my thigh. Too far back for me to comfortably be turning I guess because I ended up not going very deep and then getting a side cramp and almost jumping. I was able to slowly inject the HCG without the cramp getting to the point of ‘jumping’ pain. However (again) I am concerned that the needle was not deep enough info that back thigh and I can’t find ANY ingot on this. The area didn’t bubble up like I’ve heard can happen if you go to shallow into the skin. But it DID bruise immediately. Does anyone have any insight into my problem?
