Hi 28f...while I was about to awake I was feeling pain in hand..actually I had a sprain so thought it is that and left it for few min later when it became too much painful I saw that it was a Cockroach bitting me on hand ...is it dangerous will the pain subside automatically?actually due to my ligament injury yesterday doctor applied some kind of wax to hand ...I washed it away but still I don't know how the cockroach bite me..it's very painful..
