Low-grade fevers weeks after COVID: Is this common with long COVID?

Covid January 2021, positive test, very sick for about two weeks, temp 101 - 102. A full recovery by March of 2021.

Woke up in the middle of the night with what felt like exaggerated symptoms of covid Aug 1 2022. Went to ER and tested negative. Doctors said they'd seen plenty "covid pneumonia" that tested negative, and diagnosed me with Covid Pneumonia from a lung MRI or CAT - cant remember which. Temp 100.1 . Over the next week or two I improved and fever was only in the 99's. No improvement since then (today 1/15/2023) - just steady malaise that comes and goes in various strengths. Fever sub-normal in the 97's or low 98's in the morning, and usually 99.5 to 99.9 about 3 or 4 in the afternoon till bedtime. I know them minute my temp goes from 98.6 (normal) to 98.7. Once fever crosses the normal to "just above normal" is the same "fever feeling" as higher 98.+? fever. When it gets to the 99's I KNOW it and feel worse.
My symptoms are brain fog and confusion( maybe because I am 79), occasional tremors, fatigue, shortness of breath , overwhelming desire to sleep at times when my fever is in the 99's, slight headache sometimes. I never sleep during the day as I already have trouble sleeping through the night. Wake up every night at two and four thirty and go back to sleep, up at 7 for the day, asleep by midnight every night. I'm a 79 year old female with Sjogren's, other auto-immune complications, arthritis, history of several pneumonias before covid. My recovery, although not complete, is a great surprise as doctors warned my history did not bode well for covid recovery. Not only was I vaccinated IMMEDIATELY upon each one becoming available, but always masked as well. Now I am still super isolated and careful, masked around everyone, no indoor restaurants, very little grocery shopping. Dr. appointments with every specialist one can think of are my social life. I live alone, and glad to have kids near enough to help if necessary. My mother was a nurse and a visionary. She said an invasive virus was in humanity's future once antibiotics became abundant. Although antibiotics treat bacteria, she felt the entire immune system would become affected so that viruses could thrive more easily.
I want so so much to get well. And I hope all of you out there get well too. 🙂

I tested positive with Covid 7/4/2022. Fever of 101 , sinus congestion, cough. Sick for 3 weeks. The 2nd and 3rd week I had low grade fever 99.0-99.6 along with extreme fatigue. Went to ER, got blood work and chest xray. Doc said lungs were clear but I probably had lung inflammation. I returned to normal after 5 weeks then started exercising, then 6th week strenuous exercise. After that my lungs started hurting, difficult talking, extreme fatigue and constant low grade fever, max 99.8. Gets worse upon mental or physical exertion. This went on for 2 weeks, contacted my PCP. He told me I probably overexerted myself. Scheduled a lung pulmonary function test for Oct 5th. In the meantime I'm struggling daily with fatigue, lung pain, and low grade fever. The only thing that helped I noticed was when I took vitamin c my temp would go down. So I started taking larger amounts spaced throughout the day and all my symptoms started improving. I also take a multivitamin and sublingual vitamin B12. I'm continuing with the vitamin C until my lung function test and we'll see how that goes.

I am recovering from my first infection of COVID19, the flu, and a sinus infection related to my sinus disease on January 30, 2023. During a two week isolation at home, I had to visit the emergency room twice. During the second visit, I spent six hours undergoing testing. It was determined that I had blood clots from COVID. I am fully vaccinated for COVID (last vaccine was in October 2022) and I received the flu vaccine the day after Thanksgiving holiday 2022.

My sleep-wake circadian rhythm is off. I am taking VitaFusion gummy supplements of Melatonin before bedtime. I fall asleep, but wake up an hour or two later and cannot go back to sleep for hours. I have intermittent headaches, brain fog where I forget things and where I put things, chest pain (administered muscle relaxant), and I am now on a routine use of an inhaler for my asthma. When I walk short distances, I am out of breath.

I developed a COVID rash all over my body, including the toes. After three weeks, the rash is starting to subside.

On February 20th, I returned to work. I am applying less effort at my work activities until I feel I can perform at normalcy.

I regularly take vitamin supplements, including zinc, vitamin D3, C, and B12.

Do you have any suggestions to improve my action plan to recover?

Thank-you for your support.

I tested positive for Covid July 18, probably had it a few days before that.
I’m much better, but still not 100%. I have lingering fatigue/ gi issues, etc. plus a low grade fever in the afternoons of around 99.6. In the mornings temp is close to normal, then goes up as the day goes on. When I first got sick temp was over 101, so this is an improvement.
I’ve gone back to my normal activities, though am taking it slower. Am I expecting too much too soon? Anyone else have persistent low grade fever?

To this day I will spike a fever of 99.0 to 99.5 every night since 2020. My normal temp is 97.5. It’s annoying and disruptive and no amount of Advil or Tylenol helps.

Thank you! That's very thoughtful 😊 my appointment went fine. I'm gonna have an endoscopy at the beginning of next month. My stomach actually hardly ever burns now that for several weeks I only ate foods that were good for ulcers in case thats what it was and also lowered how much salt i was eating. My low grade fevers are also better and I've had more nights without a low grade fever than with but idk why that is except that I did connect the days that I got extremely emotional or stressed were the days it was worse.

I'm another one. I had COVID in August 2022 but still have a few long-COVID symptoms, primarily intermittent fatigue. What's puzzling me is a persistent elevated temperature. Pre-COVID, my steady-state body temp was 97.7. Since COVID, though, it's never lower than 99.0 and often rises to 100.0+ in the evenings. I've told my doctor, who basically said, "That's interesting. Maybe it will go away in a few months." Do I care?
