I was having a lesion type thing 2-4 mm on skin of left shoulder top for like 2 month(attached collage photo) 3 days ago I pressed it with finger nails and slight blood came off and I applied a cream. It doesn't healed back in 3 days and red skin underneath was visible Today when I pressed it clear fluid was oozing from it and fluid was much as usually compared to size of 2-4 mm open wound. I am attaching pics , the pic in collage shows condition before(10days back)  and condition afterwards (today) And other pic makes you take a complete look of condition today. Skin around this feels rubbery as compared to skin normally. What could it be ..I am feeling anxious .
