I have pictures of my normal left hand pointer to compare the size difference to show the swelling. I poked the spot that was swelling ever so slightly with a needle and a small dot blood came out instantly but stopped after only about 3-4 seconds of coming out. It created a little bubble of blood no higher than 3 mm above my fingertip. I did this about 4 times until blood stopped coming out all together if I poked another small hole in my skin.

I greatly appreciate any help or advice on this!
P.S. - I'm currently a college student so my family doctor isn't exactly close to me right now. That's why I'm seeking help here first.
Keep taking the cephalexin for the full course recommended by the doctor before stopping it. (That dose is a bit low?) If it doesn't go away you would probably want to try a different antibiotic. A dermatologist might have additional ideas if it doesn't go away after a few weeks of antibiotics!
