Question: Unexplained fever 59 year old male, 5’ 11”, 150lbs:
Smoker some 40 years 1 pack per day – currently on a quit program.
March 2012 open inguinal hernia repair right side
Currently exhibit another inguinal hernia on left side with watchful waiting per GP – symptoms are slight burning after standing / walking and occasional sharp pain usually when sitting.
Looking for an answer to why I had a fever of nearly 103 for several days. My GP diagnosed it as pharyngitis, but I did not really have much of a sore throat. I did have a bit of tenderness in the right tonsil noticed mainly when I would yawn.
GP tested for strep and mononucleosis and both were negative.
Had a chest x-ray and normal
CBC With Differential/Platelet blood work with one flag, sample was taken before starting any antibiotics, and Motrin or Tylenol had been used the two previous days for fever reduction:
Platelets 76 Alert x10E3/uL 150 – 379
Six months ago the Platelet count was:
Platelets 131 Low x10E3/uL
Currently taking a 10 day course of Levofloxacin 500 mg. GP did not note any significance in low platelet count.
A year ago I had a mild fever, some redness in the throat, and tenderness in the prostate that was noted when sitting and during a DRE. It was particularly painful if I would ride a motorcycle for just 20 minutes or so. I was treated with a 14 day course of Cipro, but I really did not notice any improvement, however, since the pain was mild no follow up was done and I was pronounced cured with another DRE, which was still a bit painful.
Just before this last episode of the high fever, I had ridden the motorcycle the two previous days for about 30 minutes, which did cause soreness and a burning feeling in the prostate area. To alleviate some of the soreness, I took a warm sitz bath later that evening and followed up by sitting on a cold gel pad to lightly massage that area for a few minutes for these two days. The following morning I had the beginnings of the fever.
Suggestions on where to go next would be greatly appreciated. Current condition is no fever, but low energy level and marginal appetite - 5 days left on Levofloxacin. Dosage was interrupted for two days as I exhibited some tendon pain in the outer back of both knees. Spoke with GP and he recommend to continue after examination.

Thank you for the response.

I would still like an opinion on the prostate. Is it possible that inflammation / infection in the prostate could spread causing fever and inflammation in the throat? Would riding a motorcycle with the saddle seat applying pressure to this area exacerbate the situation and cause spreading of an infection throughout the body?
