Thank you, Valerie! I checked in with my sister and unfortunately, based on her insurance, she's stuck with the primary care provider and neurologist. However, she said that after the results of her MRI, they've both been more supportive in her care (though, I'm still upset that they didn't believe her in the first place). Here's hoping they continue providing her with the care she needs. I've also encouraged her to join a local MS support group, but she's very hesitant for various reasons. I hope she will eventually. In any case, THANK YOU so much for your kind and encouraging response. It's wonderful to know that there are people out there who care.
