DD9 has 19 of theose spots/ blisters on her thighs and behind her knees. All in a concentrated area. They have been there for towards 2 years now. We have been to the GP 4 times to be told to leave it no treatment and they will go soon. But they are really bothering her. They hurt and today one popped and was bleeding. Going to make another appointment. Has anyone please got any experience of this and know anything to get rid of them? Poor thing is in bed in tears again I feel so helpless.
