I am writing this for a co-worker. Symptoms began on Monday, April 27 with fever of 101.5 degrees, body aches, nausea, fatigue, severe pain in neck, spine and head and chills. Heart was racing and felt like vomiting. It took two days to ease the discomfort and the fever was gone. Returned to work on Thursday, April 30, then that evening was able to sleep, but woke up Friday, May 1 with body discomfort, chills, pain in lower spine, weakness, shortness of breath, fatigue and a temp of 101.5. Had been on Nitrifurantoin until a cystoscope was scheduled on Mya 21, but stopped taking the medication. What is going on?
