Pain behind right eye and on movement now gone after 3 months with blurred vision. pins & needles hands & feet. constant fatigue. possibly ms?

Possibly: You need to see a neurologist and have this evaluated asap. MS is one possible cause.

Analysis: The eye symptoms might have been a mild case of optic neuritis, or retrobulbar neuritis. Did an ophthalmologist evaluate the process? Your sensory and fatigue issues are non-specific, but do need to be assessed. Have you had MRI studies to date? Have you had referral to neurology? Cannot confirm or disconfirm a diagnosis, currently, but urge you to get consultation.
