For the last week I have been sleeping up to
viral infection may be present
HI, thanks for using healthcare magic
One of most common reasons for acute/recent onset of fatigue is an infection, particularly a viral infection (since viral infections are more common).
If the symptoms occur for a long period of time then anemia (low blood count) and hypothyroidism (low levels of thyroid hormone). An ESR can also be helpful, it goes up if there is any inflammation in the body- infection, allergy, trauma, cancer
If the symptoms continue or worsen then blood tests may be needed to check these levels.
Uncontrolled chronic illnesses such as diabetes or heart disease or other chronic conditions- can also cause fatigue
For now, the main aspects of treatment consist fluids and rest and monitoring for any specific symptoms such as pain, headache, nausea, vomiting, cold symptoms.
If any discomfort occurs, can consider the use of paracetamol/tylenol.
I hope this helps, feel free to ask any other questions
