Fibromyalgia Symptoms HOME

My sister has been diagnosed with Fibromyalgia a few years ago and some of the symptoms she is having is very concerning to the family. We are trying to understand if in fact this is fibromyalgia related or another serious issue. The following is a general breakdown of what happens when my sister has these spells. They use to happen less frequently, but are now happening two to three times a day. When a spells hits her, she starts getting quiet, she starts having slurred speech, she becomes incoherent and is not able to focus or understand what anyone is saying while having one of these spells. If she walks during one of these spells, she is wobbly and and some times needs assistance with walking. If the spell happens while eating, she seems to get choked sometimes and her appetite seems to increase more than normal....she eats large portions of food. Typically, these spells last about 15 minutes. One spell lasted about 45 minutes and it was so bad that she couldn't even eat, chew or swallow....she had no idea what was going on and her eyes looked like they were glazed and she was going to pass out. Are these symptoms normal with extreme fibromyalgia??? Very concerned!
