@hilanjd Hi and a week it's still probably a bit early for there not to be some discomfort. I remember with my first placement they actually build a small pouch of sorts on the inside to place the pacemaker in kinda like a shirt pocket of sorts. Now mine was placed about 4 inches down from.the top of my shoulder and almost directly above my left breast now im a man and I don't know if it's different for the Ladies based on mammary glands but also it takes about 6 weeks to heal. I remember that the first 6 weeks I was told light duty, no lifting more that 10 lbs and not to raise my arms over my shoulders.
I do remember how painful it was the first couple of days especially when they did an ultrasound to verify the placement. The tech had to dig that probe into my shoulder and it was intensive for a few minutes. On.thinking they usually probably did that part while your still sedated but I was fully awake and felt everything. So I hope that helps and if it botheres you too much longer I would definitely give your doctors call.
Now one other thing ill mention is mine was also pretty large since it had a defibrillator also it probably measured 3 x 2 inches in dimensions so it would sometime itch a bit and I would kinda move it around a bit to scratch it. It wasn't constant but happened occasionally.
Have a Blessed Day

Thank you so much for words of encouragement. It is still early in this whole process so I will try to keep my expectations low right now. I am using an ice bag right now to try and help with swelling. I have to go back to the doctor in a week for a wound check. The bandages were removed today and there are still a couple of small areas that need to heal.
