It was a long time ago when I was diagnosed with reactive arthritis. I remember the back pain during the night that made me afraid to fall asleep. Suddenly the bedroom would be converted to a torture chamber.

The weird thing was how I would be perfectly fine when I was awake which was when I tried to explain to doctors what happened when I slept. I don't think anyone believed me because the recommendation was a new mattress. I don't blame anyone for not believing me because I had a hard time believing it too!

This went on for a couple of months and yes they were pushing the NSAIDs. I was told to take ibuprofen initially instead of Celebrex. Later on I was told to take Celebrex because ibuprofen was making things worse.

I wound up in the emergency room severely dehydrated and thinking I was going to die. Actually I thought I had a stroke when I noticed one pupil was "fixed and dilated." That eye was responding normally because of retching. It was my other pupil that didn't dilate that got the attention of the emergency room doctor.

He assured me that I wasn't having a stroke because I was "too coherent." The dehydration prompted questions about a gastrointestinal illness. The clincher was the inflamed red eye, I really think had it not been for my eye I could have died. The inflammation in my eye was caused by uveitis which is associated with reactive arthritis.

My being HLA-B27 positive and everything that happened before showing up in the emergency room pretty much left no doubt what happened.

I'm not Jewish but that was why Reiters syndrome was changed to Reactive Arthritis. This doctor did unethical medical experimentation during the second World War.

"The arthritis often is coupled with other characteristic symptoms; this was previously called Reiter's syndrome, Reiter's disease or Reiter's arthritis. The condition was renamed to reactive arthritis because of Hans Reiter's war crimes with the Nazi Party."

I should add that an ophthalmologist treated uveitis with Prednisone. The general practice doctor didn't know I had taken Prednisone for my eye and prescribed sulfasalazine. The same night, I slept the entire night without pain. At a follow-up visits with the GP doctor, I said he cured me. He was skeptical and said sulfasalazine would not have worked so quickly. He was right because I wasn't cured. Prednisone stopped all the inflammation and pain.
