Hi, I Am Linda Ryan , 68 Yr.old W/F. I

Hi, I am Linda Ryan , 68 yr.old W/F. I am taking Tresiba and have developed a cough that I have to get up and sometimes throw up. I have water retention, even though I am taking Lasix. I have been having diahhrea, itching on my legs, and I have a lot of mucas coming from my sinuses. I just started taking Tresiba, but was on Humalog before this, and Trulicity before the Humalog. My insurance (Humana) will not pay for my meds. My question is am I having an allergic reaction to this med?
