I do not know why a bloody red welts on my face, shoulder, back, neck, and the area under my neck.
I have got it about two or three months. At the beginning, I thought I got an allergic from something, like food or the maskes. I got rid of the maskes when I got a bloody red welts on my face after I use the mask. The red welts were gone after I took some medicine and spread on medication. Unfortunately, the red welts came back on my back, shoulder and back again. So, I think it was not the problem from the mask. Maybe it is caused from lactic acid drink. Then, I got rid of it. The red welts were gone after I took some medicine and spread on medication. Unfortunately, the red welts came back on my back, shoulder and back again.
