Overall I m usually in very good health. Three days ago I suddenly felt very weak, no energy, and all my body aches. All joints, legs etc. Ache. Feel listless. Had very slight feeling of high temperature, but thermometer today says normal 98.6. Appetite is diminished, but have no upset stomach. Sinuses are not draining. No sneezing or running nose, or fever. I m trying to take in a lot of liquids; my urine is very cloudy and darker than usual. My age is 81, but I am very fit relatively. I had the customary flu shot last Sept. It s summertime here and we have unseasonable temps of near or above 100 deg. But I have avoided going outside. I live near Portland OR. Do I have simple flu or something more serious? GW
Hello, It seems you have contacted an infection. Could be flu or urine infection considering your age.  Anyway you have not mentioned urinary symptoms like burning sensation while urination or increased frequency. Since you have mentioned cloudy dark urine, it is better to get a urine full report, full blood count and CRP done. Sometimes when you are at advanced age you don't show fever, you just get constitutional symptoms.  If the count show a viral one you have a flu. Any way these joint pains and body pains are more of viral plus symptoms.  If investigations results are of urine infection you may have to take antibiotics. Hope this helps. Thank you.
