Hi. Im 36 and I have eczema that is been fairly under control. My fiance is always taking notice to any changes in my skin and she has noticed several things. I have small circular indentations on my back and when touched its extremely sensitive. Also, I get on occasion a strong tingling sensation on my back around my right shoulder blade. When I touch the area I can usually feel a small bump or two under the skin. However there is nothing noticeable on the surface. Another thing is that when popping pimples on my back, my fiance comes across black spots under my skin and when she pops them like a pimple small clear balls come out. On occasion she may get a few. While trying to get them out I can begin to feel numb in other areas of my body. Could you tell me if I should be concerned? I did smoke for 15 years but have quit 2 years ago. Thank you.
