[59F] Experiencing severe fatigue and additional symptoms

What might be happening

Based on the symptoms you've described, there are several possibilities:

• Chronic Fatigue Syndrome (CFS): This is a complex disorder characterized by extreme fatigue that can't be explained by any underlying medical condition. The fatigue worsens with physical or mental activity, but doesn't improve with rest. There is no single test to confirm a diagnosis of CFS. Your doctor will have to rule out other health problems that have similar symptoms.

• Autoimmune diseases: Conditions such as lupus or rheumatoid arthritis can cause fatigue, joint pain, and anemia. These conditions can also cause swollen lymph nodes, which could be the lumps you're feeling on your neck.

• Infections: Certain viral or bacterial infections can cause prolonged fatigue, swollen lymph nodes, and other symptoms. Examples include mononucleosis (mono) and Lyme disease.

• Cancer: Certain types of cancer, such as lymphoma, can cause symptoms like fatigue, weight loss, and swollen lymph nodes.

What you can do

Given the severity and duration of your symptoms, it's important to seek medical attention as soon as possible. Your doctor will likely want to perform some tests to help determine what's causing your symptoms.

In the meantime, try to rest as much as possible and maintain a healthy diet. Staying hydrated and getting plenty of sleep can also help manage your symptoms.

What you should look out for

If you experience any of the following symptoms, seek medical attention immediately:

• Severe pain
• Trouble breathing
• A fever
• Symptoms that are rapidly getting worse
