This is quite a shocking story; in theory I knew about the hydrofluoric acid dangers but I had never read about such a serious battery incident. Still, things could have been even worse. As SilverFox said, you should have faith in the remarkable abilities of the human body and retain a positive attitude. You will get much better, it's just that the recovery process itself might bring temporary discomfort.
Thank you for sharing this story with us. I think it will increase awareness about the dangers of certain battery chemistries and about the proper reactions in case of an accident, although it's hard to imagine that anyone would react any better than you did in the heat of the moment.
Please, keep us updated in regards to your health. Again, many wishes for a speedy and full recovery.
