 [ Symptoms ] i suffer from dyspnoea with muscle cramps in arms and feet [ Disease ] i am sorry you have had a bad experience with the emergency department usually boils do not require emergency treatment so there was no harm in your trying to treat this at home however the fact you are now experiencing scrotal edema swelling of the scrotum tells me the problem has escalated and you should seek medical attention if you have red streaks on the skin around the area of the boil or if you are running a fever you should see a doctor as soon as possible if you are not feverish you could try calling your primary care provider to get an appointment soon be sure to let them know what is going on so they can advise you if it is ok to wait hope you get this cleared up soon
