[63F] Experiencing progressive muscle weakness

What might be happening

Based on the information you've provided, possible causes for your symptoms could include:

• Polymyositis: This is an inflammatory muscle disease that causes decreased mobility and muscle weakness. It's often associated with autoimmune conditions, which you mentioned you have. It usually affects the muscles closest to the trunk or torso. A common symptom is muscle weakness that gets worse over time.

  • Treatment typically involves medication to decrease inflammation and suppress the immune system.

• Dermatomyositis: This is similar to polymyositis but also involves a skin rash, which could possibly be related to your eczema. However, you didn't mention a rash, so this may be less likely.

  • Treatment is similar to polymyositis and may also include treatment for the rash.

• Medication side effects: Some medications, including RINVOQ, can cause muscle weakness. However, this would typically not be limited to the upper arms.

  • Treatment would involve discussing these side effects with your doctor, who may adjust your medication regimen.

• Depression: Depression can cause physical symptoms such as fatigue and muscle weakness, as well as emotional symptoms such as feelings of sadness.

  • Treatment typically involves a combination of medication and therapy.

What you can do

1. Consult your doctor: Given the severity and duration of your symptoms, it's important to consult with your healthcare provider. They can conduct a physical examination and possibly order tests such as blood tests or a muscle biopsy to help determine the cause of your muscle weakness.

2. Monitor your symptoms: Keep track of your symptoms and any changes. This can help your healthcare provider in diagnosing and treating your condition.

3. Stay active: Regular, gentle exercise can help maintain muscle strength and reduce fatigue.

4. Eat a balanced diet: Proper nutrition can help your body heal and function properly.

What you should look out for

Seek immediate medical attention if you experience:

• Difficulty swallowing or breathing
• Rapid progression of muscle weakness
• Severe pain
• Fever or other signs of infection
