Sometimes the blood tests are negative early on! When MG is basically ocular only, they might not show up until later on.

Have they thought of doing a Tensilon test? If you have obvious ptosis, that would be a very good thing to do!

Also, a trial of Mestinon is a good idea. So is seeing a neuro-ophthalmologist (N-O)!

Before you go and have a brain MRI to look for other causes, see a N-O.

Watch for any signs of weakness, and report those to your neuro if they occur.

I wish I could help more.
