had a very similar, experience - albeit somewhat less violent of a reaction than yours. Got the hook in my finger while in Temagami on a Thursday on a back lake, 6 miles up from the cottage, at dusk; all by myself and no one else on the lake, Needed to navigate a small shallow stream with the trolling motor hand held and the main motor fully raised to get in and out. I managed to pull the hook out after a few extremely uncomfortable moments (especially as the bass was still jumping with the both of us attached to the stick bait). Treated it with hydrogen peroxide and kept it covered but by Sunday night when we were at home it was so swollen I knew things weren't good. Went to one emergency room, told me they had a 13 hour wait at 1:00 am. (what the HECK is a medical emergency that can wait 13 hours?!) So i said nuts to that, called my Dr as soon as the office opened , and got in there lickety split. He got that look on his face you don't like to see Dr's get, got out the big drug book and went looking for a specific prescription. Said fill it out front, start taking them right away. Double up for today. this is my email address - if the pills don't start working by the morning email me. Had a harrowing 24 hours, as I watched swelling continue and the finger go from painful to numb as it swelled. Eventually the meds kicked in and the welling went away. Everytime I get a hook or fish cut now, the scar swells up. Dr said when all was said and done that I had blood poisoning, that hooks and fish are full of bacteria and to be very aware.
When going away on trips now I get a general screen antibiotic prescription from the doctor and fill it before I go.
Glad to hear everything turned out well with your friend Cliff - and congrats on a great outing. That's a definite benefit of being retired - being available to go fishing when the conditions are prime! I sooo wanted to get out on Wednesday and Thursday of this week.
