I have been sick for a month. Started with sinus infection received amox clav and have never had reaction befor. sinus got better but cough would not go away and developed itching and rash on hands and feet. went back received inhaler and cough pills helped and prednisone for itchy rash. but stopped inhaler because it you rash worsened. felt good this weekend worked with sawing wood and insulation. now today itchy palms and feet along with just a rash on arms and thighs
