Swollen nodes symptoms and conditions

I have been on Doxy since the 29th for possible pneumonia/sinus infection-deep cough,swollen nodes sick for almost three weeks.
I am pretty healthy at 39 but got this whopper that wouldn't let go.
The doc prescribed this Dox 100mg,along with Prednisone. My cough is clearing up,feel better overall, but have had very vivid, chaotic, and scattered dreams.
A little GERD (I have Barretts Esophagous so wouldn't feel too much hburn) today, but the main issue was the pill, so strong I projectile vommitted three times yesterday, have had major runs, and dry skin.
It works best for me after food and loads of water/vitamin water, and staying very hydrated. I drink a lemon ginger tea to soothe my stomach.
Other than that I am in Arizona and haven't had any sun-sensitivity issues.
I have had a headache as well for two days, but the vomitting could have brought that on, I almost popped a gasket it was so sudden.
Well, it seems this one is a doozy, get all of the facts on it-especially the NO DAIRY when taking it...
Hope all readers feel better!

I was prescribed Levaquin 750 q day for what appeared to be a breast abscess and swollen nodes in my left axilla. By day 3 I didn't feel a whole lot better, the infection didn't seem to be improving greatly, day 4-6 spanned a weekend, by day 7 I was so miserable I checked into the ER. There they did blood work that showed that my bone marrow was completely suppressed, which meant that my body was unable to fight the infection at all. The result was a two week stay in hospital, IV antibiotics x 4 weeks, incision and drainage of stated area x 2, and a lengthy recuperation. I am an RN, have never been sick a day in my life before this episode. I am still unable to return to work because of my low white blood cell count, and will very likely have to change jobs because I doubt whether I will be able to return to 12-hour shifts on an ortho-vascular floor. I am still quite weak, tire easily, need to rest frequently, do not have anywhere the ability to work a full day that I had before this episode. The affected areas are finally healing, but it is now 6 weeks post appearance of the infection. My WBC is still about half of what is should be to be low-normal. I am being followed by a oncologist-hematologist to correct the damage that was done to my bone marrow by this dangerous medication.

My name is Evie Brien-Wells. I was prescribed Levoquin 750 q day for a breast abscess and swollen nodes in my left axilla. I took the medication, but didn't feel much better, in fact the infection seemed to be getting worse. Days 4-6 spanned a weekend, by day 7 I was so miserable I went to the ER, where they found by doing bloodwork that my bone marrow had been so completely suppressed, that my body was unable to help fight the infection. The result was a two week stay in hospital with IV antibiotics, need for incision and drainage of the areas in question x 2, and a lengthy recovery. It is now 5 weeks past my first hospital day, and my white blood cell count is still less than half of what it should be. I can't work with an immune system still that compromised. I am an RN, age 54, never been sick a day in my life before this episode. I still feel weak, altho' that is getting better every day. I still find I need to nap during the day, and that alone is very unusual for me, as I worked 12-hour shifts before this little episode. I am going to have to find a job that is less demanding, as I doubt that I will be able to do 12-hour shifts any time soon.
