Januvia and blood sugar

I have been taking Januvia for about 8 weeks. I have had severe bronchitis, and now can't get rid of chest congestion for two weeks. Seems like fluid build-up in my lungs. Before I started taking Januvia, I was so proud of the fact that I had not been ill in years. Now, can't seem to get well. I stopped taking it this morning and hope to regain my health.
I plan to see my doctor next week.

Numbness in legs and hands, weakness? the spoon in my hand didn't feel right to eat, agitated, high blood pressure, chest pains, sinus infection,
face very numb, started at the lip within 12 hours it was spreading up my face, my eyelids felt so heavy.........I went to the Dr.. he said I had sinus infection, I asked about the numbness, he said Januvia had nothing to do with it!

I left feeling like I was going crazy why all these symptoms and JANUVIA was SAFE, A MIRACLE DRUG WITH NO SIDE EFFECTS BUT A SORE THROAT!

I called 2 other doctors to verify. My dose was due, I skipped it , 4 hrs. later I started noticing a difference
