Hello

i noticed around 12 weeks ago what looked to me like a blood blister on the back of my upper arm. Slightly raised.

weeks later my husband also noticed it and took a photo for me to see clearly. It was reddish black and looked to be nodule like. I maintained it was a blood blister and attacked it with my nails ( I know stupid).. roll on now 4 weeks later and it is back. I had a telephone app with my gp sent over photos and within two days I have been referred to a dermatologist, awaiting app within 2 weeks. I am beside myself with anxiety and foreboding. I have never been a sun worshiper, however over the past 12 months have been abroad twice, had never been overseas before. Also I have used a sun bed several times In this period too. (I also know very stupid) Also it is not itchy but feels tender to touch.

thankyou in advance 

a very worried lady
