hive on forehead turning into welt/swelling
1st photo is my forehead currently, and 2nd photo is from another day where i got a hive in the same spot, just to a lesser degree
could anyone explain why its swelling like this? it started itching/popped up on saturday, didnt go away, got worse on monday, and now upon waking up today, tuesday, its swelled. it didnt feel itchy upon waking up, but the minute i touched it the itchiness came in
its usual for me to get hives in recurring spots, and sometimes they do swell like when i get hives on my chin, however they usually dont last this long
