No need to apologise for not being on, we're here as you know for you whenever you need us. The blurred vision could be due to the swelling so keep a record of it, and your symptoms ready for when you go back. As there are no changes to your field vision, and your Neurologist hasn't scheduled an urgent LP, it is a good sign that the swelling isn't at a threatening level. The swelling could just be enough to cause the double vision rather than just blurred spots. It's the blind spots enlarging that are an indicator of threat to vision, and you haven't got that. I'm sure once the LP is done the double vision will settle down.
The tingling could be due to a trapped nerve especially as you have a bulging disc, but it is possible it could also be from the pressure. Ask your Neurologist about it so he can rule in or out which one it is.
