M26, so around 2 am I had this almost instant swelling (almost looked like a hive) on the right side of my of my chest (about halfway down my torso under my armpit). It’s slightly tender to the touch, but doesn’t itch. As far as I know I don’t have any allergies to anything (outside of having seasonal allergies, which only cause congestion). The only medications that I’m on are Lamotrigine 100mg, Vyvanse 70mg, Loratadine/Cetirizine 10mg (I alternate between Cetirizine and Loratadine). All of which I’ve been taking for years. I’ve only ever had something like this happen once when I had a bout of dermatitis in May of 2021, but this feels…different (I don’t know how to explain it)
