Hi, I've just received a diagnosis 'en coup de sabre'. I'm 45 years old and noticed a lump forming on top of my head in January. This has progressed to a linear style loss of hair. The lump, can at times, feel like it should burst. The dermatologist conducted 2 biopsies which she felt were inconclusive and then sought the opinion of her colleague. The loss of hair is about 3 cm long and I can feel an unevenness on my scalp. I have prescribed a steroid cream and a review in 3 months. Just before holiday I was experiencing a strange moving sensation in my head which caused my vision to be 'wobbly' this went on for weeks, however, this seems to have stopped. Can anyone tell me what to expect and if they have this blister type lump?
