Hi, @peggi - I would like to add my welcome to Mayo Clinic Connect. Sounds like you are having some walking trouble from your stiff person syndrome and are looking for other treatment since a shortage of immunoglobulin led to discontinuance of your therapy.

Hoping that @suzanneleafbrock @trs @fivets @ndville @stiffpersonsyndrome will share about the symptoms they or their loved one has experienced and also what regimen they are on and its effects, as well as offer their support. @hopeful33250 also may have some insights.

When is your upcoming appointment with the neurologist at UW Hospital in Madison? Are you having other symptoms beyond the walking challenges?
