After making a trip to Africa I slept in a bed that had like sand on it. Now I have sand-like particles and sometimes like large salt crystals (3mm) coming out of my skin. Sometimes it is like white particles. I have about 200 of these coming out of my skin every day, all parts of the body but particularly Skalp, hands, tips of fingers and under rings, soles of feet, behind, back. I have non-healing pimple-like lesions on my thigh, chest, arm and neck made by the salt crystals.
