I'm a 32-year-old mother of two who began having mild ms symptoms two months ago (tingling, shooting pains in hands and feet). An mri showed a single lesion and the csf showed borderline igg levels (.57 igg index). The symptoms have been present over 3 months without remitting, so it's difficult to say if it's a single "attack" or a series of small ones.
With a "probable ms" diagnosis from my neurologist, would there be risks in starting interferon beta 1a treatment before a definitive diagnosis?
