This topic is about an ileostomate who is experiencing intermittent high fevers and is trying to figure out the cause. The person is immunocompromised and has considered several potential triggers for these fevers, including COVID-19, influenza, a reaction to a shingles vaccine, or possibly something related to their ostomy. Here are some insights and advice shared by others:

1. Delayed vaccine reactions can happen, especially in those with autoimmune conditions. Some people have reported fevers after receiving the shingles vaccine or the Pfizer COVID-19 vaccine.

2. Other common sources of fever for ostomates include infections, inflammation, blockages, medication reactions, and poor circulation. One person mentioned experiencing "phantom fevers" every few months, which were not linked to any major infection or cancer.

3. It's helpful to keep a detailed log of fever episodes, noting the temperature, duration, and any accompanying symptoms. This can be useful for future doctor visits. Regularly checking your temperature, even when you feel well, can help catch low-grade fevers early.

4. Pay attention to additional symptoms such as sore throat, the type of cough (dry or productive), muscle or joint aches, changes in ostomy output, abdominal pain, and headaches. A fingertip oximeter can help differentiate between a cold or flu and possible COVID-19, with readings in the high 90% range being reassuring.

5. For short-term fever control, acetaminophen or ibuprofen can be used if the fever responds and lasts no more than 48 hours. Seek medical care if the fever is accompanied by severe pain, suspected blockage, breathing difficulties, or sustained low oxygen saturation.

6. Supportive measures include staying hydrated, taking vitamin C, and using warm socks or hot-water bottles to help with cold extremities. Continuing COVID-19 precautions and testing is important, and it's good to know that getting tested was the right decision.

7. Medications and devices mentioned include azithromycin (Z-Pak), acetaminophen, ibuprofen, a rescue bronchodilator inhaler, the shingles vaccine, the Pfizer COVID-19 vaccine, and a fingertip pulse oximeter.
