Yah, can't wait for that bill... However, the antivenom for bark scorpions is made from horse plasma. One question I thought was weird prior to them giving it to me was if I was allergic to horses. It made sense when I got home and researched.
I wasn't in a position to say no. I was at the highest level of reactionary symptoms. But, the docs all but refused, blaming cost. My GF had to call our insurance Co. before they would do it. We had to all but beg them give it to me. I was on hour 8 of neurological breakdown...almost total numbness, but with hyper sensitivity in some areas. Violent muscle spasms and convulsions. Near blindness from extreme nystagmus.. With reactions as bad as mine, heart failure is a real possibility.
The antivenom took the muscle spasms/convulsions away in under 20 minutes. At about the 45 minute mark I could read a text message at normal font. Around an hour and a half I was getting discharge papers.
"Typical" bark scorpion reactions are local burning and possible swelling for 2-3 hours. Maybe some numbness...
