Back to life again...

So this has been an interesting week thus far - Sunday, John and I brought our parents to see the house we had the offer on, and after them going through it all, we realized this was not the house we want, and ended up backing out of the deal yesterday.
Sunday night, John and I were just hanging out at home, when suddenly, I started to not feel so well. By 8:30 I was in bed, and by 9, I was EXTREMELY sick - I won't give you the details, but I'll put it this way: Picture the Norwalk Virus, or an insanely bad flu - now picture it all coming on within 20 minutes. But on top of it, I was having pain in my kidney area. I've had two prior kidney infections, and I knew that if it wasn't treated, it could make you very sick and then spread into your bloodstream. So at midnight, I had John drive me to the ER. At first they thought they would just give me something for nausea and maybe an antibiotic via IV, but when they drew blood and got the results, they were like "Umm, we're going to have to admit you - you have a very serious kidney infection and you need IV antibiotics." I had spiked a fever of 102.1 and was seriously dehydrated (as I had been unable to keep even water down). So at 2 in the morning, I was officially admitted into the hospital. John stayed with me until about 3:30, then went back home to sleep. He came back the next day though, as did my mom after she got out of work, and I spent a lot of time on the phone with people. I got IV antibiotics about every 12 hours, which made me kind of drowsy. My fever kept going up and down, but fortunately it was not even reaching the point it was at before. Finally, today, my doctor came in and said they would start me on oral antibiotics, and depending on how I tolerated it, I would be released tonight. I slept pretty well last night, with my fever breaking sometime during the night. It kept going up and down a little, but it was minor - like from 99.3 to 97.1 to 99.3 again. Fortunately, I tolerated the medication just fine, and was discharged around 5.
So now I'm home, and it's back to life as usual. I have to follow up with my doctor in 2 weeks, and we'll see what's going on then. I hope I'm fully better by then. I still have some slight pain in my kidney area, and I also have some pain in my upper back, which is weird, because I didn't have that before. I'm attributing it to the incredibly uncomfortable beds.
So I'm going to go relax some more and just be happy to not have an IV in my arm anymore.
