I have a spot that looks black in color and red around it and its very painful. it seems has if it appeared overnight. it does feel like a small lump, what could this be? its located on the side of my hip more towards my back.

Bite: I suspect an insect bite. In view of the associated pain it could be spider, ant or wasp. Observe for spreading redness which would possibly indicate a secondary bacterial skin infection and this requires an evaluation by a physician. In the meantime, wash it with soap and water and apply an antibacterial ointment. Severe pain often occurs with brown recluse spider bites and these should be treate
