I recently had to remove porcupine quills from my dog, I pricked my thumb with one, the last couple of days it has been sore to the touch, today I guess not so bad cause when I finally looked at it I noticed there was puss under the skin around my nail. I percied the skin and removed puss and cleaned it with peroxide, I cant see if there is anything in there but it is very sore again, I have also notices the last couple of days I have been really ichy all over for no reason and tired.lisa
