Hi, just wanted to know if there were many of you with headaches or migraines as a main symptom. As myasthenia is under researched like a lot of conditions and I see many mention vertigo like symptoms or tinnitus as an early symptom as well. As many of you know the information out out there state muscle weakness and fatigability as the main symptoms and some texts specifically say 'myasthenia does not cause headaches'. Which to me doesn't seem quite right. So I'm interested to see what other feel/think.
