A few times, some good, not so good experiences.
I cut my finger, nearly off with a steak knife. Tip, never put on pipe insulation in the dark, feeling your way around making the cuts . I didn't notice I had done much damage to my hand until I pulled back my hand and blood was gushing everywhere. Not sure why I didn't feel the cut as being that bad. I ran in the house and grabbed the first thing I saw, a sock on top of the dryer, wrapped it up and went to the ER. The intake lady asked my why I was there, I told her I cut my finger nearly off, so she said let me see it. I told her it was really bad, she wanted to see it anyway. So I removed the sock and blood went everywhere, she started screaming, put it back, put it back ! I still laugh when I think about it. They stitched it up, gave me a tetanus shot and sent me home. Healed well , though no feeling in the tip of the finger.
Worst experience was when I had a tooth infection. Doctor gave me Clindamycin as an antibiotic. After the second day taking it I started vomiting, couldn't walk and had to call rescue because I kept passing out. The ER doc comes in , sees me shaking, pale skin, and covered with sweat, so he gives me IV fluids, and starts drilling me on what drug was I on, when was my last fix, and who did I think I was kidding ? He ran a drug test and because it came back positive, he assumed I was having withdrawals. He didn't bother to look that it was positive because of the Vicodin that the ER doc gave me the day before. I stayed in there for 3 more hours till I felt better and went home.
Next day I was right back , same symptoms and again the same DR in the ER claiming I was a addict. I got pissed and asked to see someone else, the DR told me he was the only one there and I would have to settle for that. I got even more irate and told them to call someone. Finally he called in another DR, who was not happy to be coming in on a day off. He walked in , looked at my chart, asked me if I was telling the truth about not being an addict, then requested some lab work. About two hours later he walked in and said the problem was I was allergic to Clindamycin and that if I had continued to take it , it would have killed me.
