Sorry to hear of your difficulties right now. That's a frustrating symptom.
I tend to slam into doorways all the time (always on my right side too) I'll get myself even with the doorway and as soon as I start it BAM! slam the whole right side into the door frame.
On those days, I stay away from cooking in the oven because it will LOOK like I have 6 inches until the pizza is touching the rack, when really my hands have been sitting on a 400 degree rack for 3 seconds before I realize what's going on, I also do not get behind the wheel on those days, as it's much like being drunk, car looks like its 3 blocks away however its a couple of yards. SCARY
and I most definitely have almost knocked all of my front teeth with a coffee cup thinking I had inches before I was at my mouth when really I have already slammed this thick piece of hard clay through my front 4 teeth.
I find I am hazardous to myself at times.
