Cosentyx (secukinumab) side effects

I am at my wits' end when I took the biologics Cosentyx. I am depressed and thought of many bad things about my life. Aside from plaque P, I also developed psoriatic arthritis in my fingers. So painful at times. My Rheuma put me of C albeit so expensive. One pen dose of 150ml made the difference. It worked! 4 months no psoriasis, no pain. But it came with a price. My cough was relentless, Sore throat kept coming back. Myalgia. Colds. Pain in stomach. And then finally DIABETES. My immune system was so down that all my childhood illnesses came back. I am now on meds for my diabetes and metformin plus strict diet. I stopped taking Cosentyx after one dose, but I still have 5 pcs in stocks.
