Hi Steph,
While I have not been through what you have, I suffered a lesion in my brain and have similar pain and weakness, but down my left side from injuries and Neurological Hypersensivity.
Damage to our brain is probably the scariest injury one can suffer, I will not know until the end of March whether mine was caused by a stroke or something else. We always worry thst we are going to lose a part of that which makes up 'I'.
Yet, here you have found a caring community, one you can share your thoughts and fears with in the run up to your operation. Try visiting the Sanctuary for an uplifting experience.

Dave.
