A while back, an ingrown hair appeared on my 19 year old son's stomach. He pulled it out and that was the beginning of trouble. Every day, the waistband of his pants would rub on this area and soon it started to become red and swollen. The swelling extended out from his body only 1/2 inch but it soon became 4 inches wide! It was huge and I became very worried. I think it was a boil, maybe a cyst. I don't know. There was a hard lump in the middle which was probably 1 and 1/2 inches across. We had purchased Mesosilver in a spray bottle so he began spraying it on several times a day. Slowly, the redness and swelling began to go down. It took a full 3 weeks but this boil completely went away, including the hard lump. When he was spraying the Mesosilver on, it never drained or was painful. When it went away, my son stopped spraying it on. It has been 4 months now and it has never returned. I am so glad that Mesosilver took care of this problem.
