Fatigue and Chronic Pain
Functional Medicine Care at Functional Health Institute | San Diego & California Telehealth
Chronic pain and fatigue often co-occur and are common in autoimmune and inflammatory conditions. At Functional Health Institute, we provide personalized, root-cause care for patients experiencing persistent pain, exhaustion, and cognitive symptoms such as brain fog, guided by Smitha Reddy, MD, a Board-Certified Rheumatologist and IFM-Certified Functional Medicine physician.
What Is Fatigue & Chronic Pain Management?
Fatigue and chronic pain management involve a comprehensive, multidisciplinary approach to help individuals manage ongoing exhaustion and pain lasting weeks, months, or years. These symptoms are commonly seen in conditions such as:
- Autoimmune diseases
- Fibromyalgia
- Chronic Fatigue Syndrome (ME/CFS)
- Inflammatory and degenerative arthritis
- Post-viral syndromes, including Long COVID
Fatigue is a persistent feeling of physical or mental exhaustion that does not improve with rest or sleep and interferes with daily function.
Chronic pain is pain lasting longer than expected for normal healing, often persisting for months or years. It may be constant or intermittent and can significantly impact physical, emotional, and cognitive well-being.
At Functional Health Institute in San Diego, we focus on identifying why these symptoms are occurring, not just suppressing them.
