Some people may have fatigue which has a big impact on them. For other people, it may have less impact. You may also have good days when you feel less tired.
You may have no energy and feel weak, and find it difficult to do the things you used to enjoy. Even the smallest things may make you feel worn out. It can be difficult to tell in advance when you will feel tired. Even after sleeping, you may still feel tired.
Fatigue can limit everyday activities, like working or household tasks. Fatigue can also affect your relationships with friends and family. Some people may feel guilty if they can’t play such a big part in family life. It can be hard to explain to other people how you feel and how fatigue affects you.
Some people have problems concentrating or remembering things. It can be very frustrating not being able to do things you have always done.
People often find fatigue upsetting. It can be difficult to cope with, and may make you feel down.
People sometimes worry that fatigue is a sign that the cancer is getting worse, but this isn’t necessarily the case. Although people with advanced cancer that has spread may start to get more fatigue, people who had early cancer also often have fatigue.
