Infected insect bite in hand?

Infected hand. Insect bite can be infected with routine skin bacteria however more exotic microrgansms are possible. Damage from the bug bite itself may be mistaken for an infection when in fact it is actually skin necrosis or an allergic reaction. Make sure it doesn resemble a recluse spider bite or something similar, get evaluated medically, your pcp or the er is a good starting point and/or see a hand surgeon.
See doc. If the bite is truly infected, it will need to be seen and treated. Do this asap.
