Hi everyone this is the first time I have applied to this forum. I had my thymus removed in 2001, as I had a tumor on it. I had symptoms that started in 1998, the symptoms started on the day I lost my father. The drs kept saying the extreme weight loss from stress of losing my father. 2000 saw another Dr sent me straight up to hospital for a MRI. Following year had to have the operation in London. Following this I’ve been in remission since. The last year I’m back on 60mg of pyriodstigmine, recently apart from choking I’ve been getting a lot of pain in my gut and chest. I’ve been putting this down to heartburn. Reading the comments I’m now wondering if this is part of MG. I’m so sorry for long winded text. Looking forward to seeing what you all think Yasmin.
