Hi Christy...good that you joined us...welcome on board !!!  My Cara is only 7..so wouldn't be much of help or much aware of what you described...but very much where you had surgery...you must have increased blood flow to a certain spot of your brain that deals with senses...but while I don't have MM I have B12 defiency (pernicious anemia)...lack of B12 which would be lack of oxygen in red blood cells that go to the brain...so for almost a year of being misdiagnosed ...with MS like symptoms..my senses decreased so much to a point where I wasn't feeling much, smelling much nor thinking straight....as soon as they figured out what my problem was....8 straight days of B12 shots....many things came back and I like you...was going...oh it smells so good, the wind outside feels wonderful, everything so much clearer...a wonderful feeling......so you are indeed getting more oxygen to your brain if your senses are crispier and sharper.... ;...awesome feeling isn't it !!!

Look forward to more posts from you,  hugs, CarasMOM
