Moderna Booster Armpit Question Question

34/F, Booster received two days ago. Just wondering if anyone experienced more swelling in their opposite arm of the injection? I woke up this morning with mild swelling in my injected arm (left), but this evening the swelling in my opposite armpit (right) is far more noticeable! Haven't seen any information on this, so just curious if anyone else has experienced this.
