G'Day, Johno:
CSF leaks are becoming less common with AN surgery but are still a set-back, considering that they follow major surgery. Fortunately, you seem to be on the mend now and ready to begin your recuperation, even if with a bit less gusto than you had immediately after your initial AN surgery. Aside from ending your steroid intake, that's likely just an indication of your emotional readjustment to the realization that healing takes time and simply having the AN tumor removed is not necessarily the end of the 'journey'. How we wish it were!
Taste issues are not unusual, post-op or, in my case (and others), pre-op. Due to the AN tumor's nerve involvement I lost much of the ability to taste prior to my surgery - and dropped over 30 (unwanted) pounds due to a sharp decrease in appetite. Everything tasted like cardboard. Post-surgery, my appetite returned along with my ability to taste (except for a few tiny spots on my tongue) but, luckily for me, my metabolism re-shifted back to it's original high rate (that had diminished during middle age) and so, I didn't re-gain the lost weight. I've since put on a few pounds (about 7) but I'm still well within my normal weight range (22.6 BMI) and I certainly hope to remain there.
I also hope that you'll regain your normal sense of taste, your vision will clear and that the palsy issue will resolve, soon. You've got enough to deal with.
I believe we all appreciate your detailed account of your experiences and look forward to reading future messages from you, here.
