I have been suffering from intense itching on hands and around fingers. It is becoming so itchy that I am intensely scratching them and so the skin is removed and there is minor tiny bleeding spots. After these becomes very painful. Sometimes there is oozing of small amount of blood from them. Also same type of lesion in feet.  Many itching and small spots overs trunks also. What may be cause. What to do now. Plz give some advice. It is becoming very irritating.
