When to Contact a Medical Professional
Call your health care provider if:
- You have other symptoms with the malaise
- Malaise lasts longer than one week, with or without other symptoms
What to Expect at Your Office Visit
Your health care provider will perform a physical exam and ask questions such as:
- How long has this feeling lasted (weeks or months)?
- What other symptoms do you have?
- Is the malaise constant or episodic (comes and goes)?
- Can you complete your daily activities? If not, what limits you?
- Have you traveled recently?
- What medicines are you on?
- What are your other medical problems?
- Do you use alcohol or other drugs?
You may have tests to confirm the diagnosis if your provider thinks the problem may be due to an illness. These may include blood tests, x-rays, or other diagnostic tests.
Your provider will recommend treatment if needed based on your exam and tests.
