High fever lasting for 5 days
Can anyone help me with some answers for this? My boyfriend 25 has rheumatoid arthritits for 2 or 3 years now. On Wednesday night he started not feeling good and on Thursday he had a low grade fever. Thursday night his fever was 103. Over the weekend it would dip from 98 and he'd be feeling okay then would shoot up to 103 again. No inflammation or any other symptoms other than fever, fatigue, sweats and chills. We went to urgent care told them he was on immuno-suppressants with a high fever. They took a swab and came back negative for covid or the flu and took a blood test. Still waiting for blood tests but that was 2 days ago and they sent him home with nothing. We're extremely worried cause theres not much info on the internet and a on and off fever this high is concerning. Has anyone been through this? We plan on contacting his RA Monday.
