It makes almost 3 weeks that my eyes are red and iritated, last week I also had some problem in my throat and I still have the same problem today( sore throat). My physician did some test to see if it was a virus, but come to the conclusion it was most an allergic reaction to something. I started using minoxidil on july 15. It is possible that the minoxidil is the cause of this? because at the moment I am looking at everything that could cause this.
