I do not understand all of this you are experiencing, though do know that with the visual problems and disturbances that are not something that is a 'usual' for you, then I would not hesitate to see a Neruologist for at least a consult, and then from there find out your options, if anythign at all, you would benifit by having some peace fo mind and reassurane.
Hope that you contintue to let us know how things are going for you . Peace and Hope I extend to you - 'I.H.'
