Heyo. SWIM took a few "stabs in the dark" last night, and tonight (about 24 hours later) has a slightly painful tingling feeling in hand as well as inability to type/use fingers without shaking. Tried a warm compress, tried massaging it, didn't help. The injection site is clearly bruised and there's a somewhat solid lump next to the veins--kind of feels like scar tissue, squishy, moves around a little when you massage it. Also--there is a swelling-type pressure in the hand. Kind of like the feeling when you tie a rubber band around your hand and cut off the circulation for too long. Someone said this has happened to them before, is most likely a nerve, and will resolve itself within a day or two. SWIM does recall an almost electric feeling sting when the missed shot occurred. SWIM has a pretty good medical background, it's not an abscess, there's no numbness in fingers or anything, just the shaking and pressure feeling. Pictures below--does this sound familiar?
