I do have an eye droop and double vision which the Mestinon does no really help at all. As for the Tensilon test, the neurologist put hi hand on my forehead and lightly held it down while asking me to raise my head. I couldn't do it, I wasn't even aware my neck muscles were that weak, I just thought I must have chronic neck problems. After injecting the Tensilon I could easily lift my head and could feel the difference in my strength, bu t like I said before this only lasted a minute or two.
I have a prism for my glasses that helps with the double vision and as soon as my severe reflux problems are resolved I will start prednisone in a small dose.
