Hi @nicleelee. I have some further info since my post on my experience, and we may have something different as I had new symptoms appear, but hopefully my info helps you out.

Beginning just after my last post (six months ago) the pain went away just after I completed my regimen of Cephalexin. I wasn't sure if that was incidental or coincidental as the pain seemed to always go away after a week anyway. Sure enough, about a week later the pain returned, and during the next two months I'd get it just on the lower left side of my nose every two weeks, and it's last about one week.After this happened a few times I also began to get a small bump inside the lower left side of my nostril, close to the opening of the nose. I'd have the pain and bump for about a week, then it'd go away and appear a week or so later. I made a trip back to the doctor thinking it might possibly be a clogged pore or ingrown hair, but I had no further success as I was giving medication that didn't seem to work.

In the late fall of last year I then started to get a slight redness at the bottom of my nose on the outside each time I'd get the pain and small bump inside my left nostril. I then very amateurishly self-diagnosed myself with nasal vestibular furunculosis. I then did a little home remedy twice a day that I found online, where I'd mix a small amount of hydrogen peroxide with baking soda, which I'd then apply inside my nose with a Q-Tip. After letting this solution dry, I'd then apply a small amount of Neosporin ointment inside my nose. In a few days the problem went away. I never experienced in my head while pressing on the nose, as all discomfort remained local.

I hope you can find a solution for your issues soon!
