It started 2 days ago when a cut on my pinky became swollen, so swollen i had issues bending my pink and it hurt to the touch. The swelling began to subside but i began to notice redlines extending from the cut down my pinky following a vein up my arm. Soon after bumps began appearing on these veins. 4 of them all hurt to the touch there not pointy or sharp just sore. I began taking antibiotics and the red lines have been subsiding but the bumps havnt. this morning i realized there is now a bump on my neck. What could this be? is it life threatening. i need a diagnosis because no one has supplied me with on yet.
