[18F] Experiencing dry mouth, joint pain, and fatigue

What might be happening

Based on the symptoms you've described, here are a few possibilities:

• Sjögren's Syndrome: This is an autoimmune disorder characterized by dry mouth and eyes, fatigue, and joint pain. However, you didn't mention dry eyes, which is a common symptom.

  • Treatment typically involves managing symptoms. For dry mouth, this can include sipping water, using artificial saliva, and avoiding medications that can cause dryness.

• Dehydration: This can cause dry mouth and fatigue. However, you mentioned that you've been drinking more water, which would typically help with this.

  • Treatment involves rehydrating by drinking fluids and eating foods high in water such as fruits and vegetables.

• Hypothyroidism: This condition, which involves low levels of thyroid hormones, can cause fatigue, joint pain, and dry mouth.

  • Treatment typically involves taking synthetic thyroid hormone.

• Anemia: This condition, which involves a lack of healthy red blood cells, can cause fatigue and sometimes, dry mouth.

  • Treatment typically involves taking iron supplements or changing your diet.

The rashes you mentioned are a bit more difficult to pin down, as they could be due to a variety of causes, including an allergic reaction, an autoimmune disorder, or even stress.

What you can do

It's important to make an appointment with a healthcare provider to discuss your symptoms. They can perform a physical examination and possibly order tests to help determine what's causing your symptoms. In the meantime, continue to stay hydrated and try to get plenty of rest.

What you should look out for

Seek immediate medical attention if:

• Your symptoms worsen or you develop new symptoms
• You have difficulty swallowing or breathing due to your dry mouth
• Your joint pain becomes severe or is accompanied by swelling or redness
