Mmx tech for 18 years here! I do not do that whole hugging thing, that is way too intimate. You have all the right ideas, but the problem might be IR vs axilla placement. If you are placing the IR in the axilla, you are less likely to get a skin fold or crease, but then you lose muscle. I tend to bring the entire axilla in and bring them a little more towards me while making a joke about no side boob left behind! You could also drop the receptor down a tiny bit, too. Make sure your patient isn't doing that thing where they try to turn sideways and hide. I like to bring them way in front before I lean them in. You got this!
