Thanks for sharing, clweiss71! I'm sorry to hear that you struggled with a sinus infection, but I'm glad to hear that treatment with antibiotics was able to clear things up, and that the infection has stayed away! Interesting to read about the low iron! Makes sense! I'm curious to see if this makes a difference, and hope you'll share the results with us! Sending positive wishes your way if you're trying this soon! Also, I'm so glad to hear that you've been able to see some improvement on the cosentyx! So awesome!!! Please keep us posted! -Casey, Psoriatic-Arthritis.com Team
