It is vary hard when you was doing so great, feeling so good to suddenly feel any of the symptoms. I felt wonderful after the 10 plasma's I had. I had my last one on the 8th of March but on and off you can feel your symptoms and that just scares me as I imagine it does anyone with MG when you feel "normal" to suddenly go back to...'not again' I know i am just rambling on but let me tell ya all you can do is ... Try your best, and don't over do anything ... As kathie said above, Rest...And def see your neuro.
We all feel your pain and emotional upset especially when your doing so great for so long then suddenly you feel MG...
Ice is wonderful by the way, also air conditioning is a must as Kathie said. Heat just sucks the life out of us.
Godbless you
