There are many causes of foot pain. Not all is MS or plantar fascitis.
One overlooked cause is reactive arthritis, which is an autoimmune disease. Another cause is gout or pseudogout.
I'd go right to the chase... see a rheumatologist.
Spreading to other joints is a serious thing so please do get it checked out.
