I had a severe lupus flare in mid-Jan.2012 and developed pleurisy and a right pleural effusion.My sed rate was 60 and my CRP was 113! In Nov.2011, my sed rate was 15 and my CRP was 1.2. On Nov.14,2011,I had my semi-annual teethcleaning. I was given Amoxicillin 2 Grams by mouth before the cleaning . My dentist recommended that I have a dead,cracked tooth extracted.Prior to my appointment with the oral surgeon, I took Amoxicillin 500mg 3x/day for 1 week. So on Nov.28,2011 I had that premolar extracted. No problems with procedure.I fly to Los Angeles and Phoenix for the x-mas holidays. 3 weeks later, I fly home to New England and I become short of breath,have pain in my right chest and run a high fever.After taking much medicine(IMMURAN, PLAQUENIL AND PREDNISONE)FOR 5 MONTHS MY RHEUMATOLOGIST AGREED I COULD TAPER OFF PREDNISONE WHICH I DID ON MAY 23,2012. ON JUNE 11,2012 I WENT TO THE DENTIST FOR MY SEMIANNUAL DENTAL CLEANING. THE STORY ENDS WHEN .ON JUNE 25,2012 I STARTED C/O OF JOINT PAIN, FEVER,HAIR LOSS AND FATIGUE. I AM FLARING AND BACK ON PREDNISONE. I AM 67Y/O AND HAVE RA AS WELL. I WAS DIAGNOSED WITH LUPUS 4 YEARS AGO.
