Can't bring arm across body
I just had my first PM implanted on 12 Sep (3 days ago). I've noticed that when I try to bring my left arm (affected arm) across my body, it's extremely uncomfortable (ie, far more comfortable than any other movement with the arm). My PM is implanted subcutaneously in the area where that movement occurs (below the collarbone, above the armpit, very close to [almost seems to be along the line of] where my shoulder bends to allow pulling the arm across the body).
When I try to make this movement, it feels that the PM is not in the right place and is physically interfering with this flexion. The movement seems to be disrupted by a combination of extreme discomfort and a physical barrier (ie, the PM spanning the space where that bending should occur) - although maybe it's just the pain causing me to stop the movement. As instructed, I took the sling off after the first day and tried to use the arm for light tasks. Everything else is mildly sore, as expected, but this movement seems impossible.
I'm a tiny adult (almost 5'0" and around 100 lbs) and I'm wondering if what I'm feeling is typical for the early days of recovery or if the device placement is a bit too close to the arm for someone my size.
I'm not happy about the scar, but I can live with that. However, a loss of function/range of motion would be devastating.
Anyone have a similar experience? Is this normal? Resovlable over time with some light "exercises" of the arm? How long? Abnormal?
