While many autoimmune conditions have their own unique manifestations, early symptoms of several diseases can be very similar, including:
Fatigue
Sore muscles
Swelling and redness
Brain fog and difficulty concentrating
Low-grade fever
Numbness and tingling in the hands and feet
Hair loss
Skin rashes
Furthermore, some autoimmune conditions experience periods of remission and flare-ups, such as multiple sclerosis, rheumatoid arthritis, and psoriasis, while others tend to progressively worsen over time.
