The NHS advice on long Covid says people who are recovering from an illness often report feeling a little better each day, and it can take time to fully recover.
It says: “With Long Covid you may feel fatigued after activities which were not previously difficult to cope with and this can affect your quality of life and ability to function as you did previously. This is more likely to occur at the end of the day or at the end of a busy week.
“Sometimes people experience a number of other symptoms worsening after physical stress. This could include brain fog, muscle aches or headaches alongside increased fatigue.
“Clinicians may call these ‘post exertional symptoms’. They are not in themselves dangerous but can affect your quality of life.”
