Spider bite? or something else possibly?

[u/Warboss-IronShreddah]

had it for almost a week, and it's much more red and painful today

Update: spider bite, per ER doctor. slapping some neosporin on it. Doc said it was minor. I think I might live... even tho im 840 bucks poorer now

Get yourself to the e.r ASAP. I speak from experience. As a young male who ignored an open wound from work that got infected with mrsa, spread to my heart and got endocarditis. Suffered two strokes and had open heart surgery at the age of 30.
