Yes, thanks. Two weeks ago I had a low fever, chills, muscle aches. After three days, I say my family doctor who thought it could be Lyme disease and he took a blood sample and prescribed wo days later, the test was negative and the antibiotic had not relieved conditions. Concurrently, I had intense pain in feet and ankles when standing/waking. Also my both hands wee swollen and painful. I was admitted to the hospital in order that extensive blood tests. I entered last Thursday and was discharges on Saturday evening. Since then, aching feet and hands have improved gently. The blood tests have not been able to identify the cause of the problem. An infectious disease doctor, prior to final blood work, thought it could be parvoB19 virus. However, that has not been confirmed by tests. Do you have any thoughts on this myster.y condition? Thanks.
