Hello, I always have a burning smell when I breathe through my nose or mouth. Could this be a side effect of my medication?

Hi, I have been on a new medication of Estradiol and Doxycycline since December 2017 which was added to my Crestor and Synthroid. A week before Christmas, I had an episode where my nose and back of my throat burned, so I thought a cold was coming on. But the cold didn't happen. I continued to have this sensation which changed into a burnt smell (the smell felt is identical to the one of a food that has sunk in the bottom of a running oven). I still smell it, everywhere I go (office, work, store, restaurant) at any time of the day and it has been going on for 6 weeks.

Hello, the ophthalmologist prescribed me this medicine for a blepharitis. I had consulted for a problem of dry eyes and she also found a blepharitis which she tried to treat with ointment but I had a reaction.
