[|Human|] I am a 49 yr old, relatively healthy, Asian female who started walking for exercise about 3 weeks ago.  However, every day for the past week, right around the same time (about 130 or 230 pm) I start getting the chills. When I take my temperature, it is usually around 99.5 to 99.9.  I dont have any aches or pains or infections that I know of. I have been taking Tylenol for the fever, but the next day this happens all over again. I have lost about 6 lbs since I started walking.
[|AI|]  Hi, Thank you for your query. I can understand your concerns. Rise of temperature with chills almost at the same time regularly for 1 week points towards underlying infection.However, lack of other constitutional symptoms like aches or pains suggest indolent nature of illness. In Asian countries, one need to rule out TB. Other possibility is lymphoma. You need physical examination and baseline investigation like complete blood count, peripheral smear for malaria parasites, Urine for routine analysis and ESR (fasting). Regards
