Experiencing Blurred Vision , Breathlessness From Left Nostril After Steroid Treatment

I ve been having a problem, been taking care of it, but it would be nice just to have someone calm my nerves. In Jan I saw a ENT Surgeon about a weak left nasal wall and she gave me a 3 month Nasal Steriod treatment until we could move onto surgery. On Feb. 2nd I had a large peice of what I believed to be cartilage fall out my nose, I had been having problems with it for a while and luckily saved the peice for my doctor to see. I recently saw this doctor again and we have now moved onto to setting up the surgery but about 3 weeks ago I woke up having trouble breathing, most likely because I like to breathe out my nose while I sleep, and it freaked me out because I felt like I was on a roller coaster and I was breathing with my whole body. Checked my heart with a monitor and I was fine and I ve seen many Urgent Care doctors in between then and nothing seems to be wrong but ever since then I ve had continued difficulty with my left side entirely. Arm, leg, hearing, occasional blurred vision only involving my left side. Is lack of oxygen out my left nostril causing all these problems with my left side?
