While many autoimmune conditions have their own unique manifestations, early symptoms of many diseases can be very similar, such as:
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 have periods of remission and flare ups, such as certain forms of multiple sclerosis, rheumatoid arthritis and psoriasis, while others consistently get worse over time.
