"For  many years Amoxicillin was my drug of choice. Last year it stopped work on me.
I had to use  Doxycycline which caused terrible burns all over my skin after 1  week of use. Even  the layer of sunscreen cream  did not prevent the burns. It did not matter - if I stayed in the shade of the tree or if it was not sunny days - I got those burns. Because I had to do multiple jobs outside the house and go to the stores - this side effect created terrible problems for me. For somebody who can stay inside for entire month - this side effect probably non existent. The drug effectively cured the condition."
