Bobby's medical Expenses

In 2009, Bobby was hospitalized because he had a stroke. At that time, we learned that it was his actually his 3rd stroke.  The year before he experienced some severe headaches but did not go see a doctor. He recovered enough to resume most everyday household activities.  In 2010, he had another stroke and was hospitalized again. He was tested for every stroke causing disease, even (MS) multiple sclerosis.  Every test came back negative.  MS does not cause strokes, but the symptoms can be similar, and the scars (lesions) that show up with MS can look like scars in the brain caused by stroke.  After about a year and a half, he was diagnosed and treated for MS.  Recently in May 2014, he had two more strokes. This time his left carotid artery completely shut down, he has right side weakness, Aphasia and apraxia.  He completely lost his ability to speak but is slowly starting to learn to speak again. He just had two stents placed into the Right carotid to keep it from shutting down like the left side.  Currently they are giving him medication to help prevent his blood from clotting.  However, he has an undiagnosed underlying disease that have the doctors here baffled.They have referred us to the Mayo Clinic where the best doctors in the country are. They have more experience with rare diseases, and will be able to get to the bottom of this. The only trouble is we don't have the money for travel expenses.  I do not yet know how long we will be there or how many trips back and forth. Bobby is only 41 years old.  There are treatments that could help him. The key is to get the proper diagnosis.
