It is not normal to have this level of pain in your joints at your age. Therefore, you definitely must see your doctor
if you have not done so already. You could start with your primary care doctor
, or you could, alternatively, set up a visit with a rheumatologist
Given the constellation of symptoms you mention, especially the presence of pain in multiple joints together with fatigue, I would be most concerned to rule out a rheumatological disorder such as rheumatoid arthritis. Make sure, when you go to see your doctor, that you mention any other associated symptoms, such as swelling or redness in the joints, skin rashes, or fevers. This information will help your doctor narrow down the list of potential causes.
In addition to a complete physical examination, your doctor will most likely want to get some basic blood tests looking at inflammatory markers in the bloodstream because, if these are positive, it is highly suggestive of a rheumatologic condition. In addition, they may obtain x-rays of one or more of the affected joints. Based on what they find with these tests, they will be able to help you decide what the next steps are.
