Poor little buddy

So I had a little scare on Thursday with my little guy. He was acting fussy all day, which I just assumed was due to his teething ( he has one tooth on the bottom so far) but as the day went on, his fussiness got worse and worse, and he was starting to act a little lethargic, which is not like him at all. He was also not eating hardly anything the whole day. I decided to take his temperature, which was a little high (100.1 F). I also noticed he kept pulling at his left ear, so I was concerned he might have an ear infection. At his point it was after 5pm, so since my doctors office was closed, I decided to take him to Kids Care. When we got there his temperature had risen to 102.5 F. The doctor looked in his ears and they were both fine. She also looked in his throat which also looked okay. She said she was a little concerned because he REALLY didn't look good at all and she couldn't tell what was wrong with him. She recommended that I go up to Primary Childrens ER to have some blood work done, and possibly a Lumbar puncture to test his CSF for Meningitis. Me being the little paranoid mommy I am, I started to cry a little. I'm glad Kevin was there to be the tough one, and to assure me that everything would be okay. When we got to Primary's they took his vitals, and his temp had gone up to 39.9 C (103.8 F), and he seemed to be increasingly lethargic, and would cry if you moved him. So they ended up starting and IV and giving him some fluid, drawing some blood, which they had to come back and poke him again because they forgot to get enough for blood cultures. They also wanted to get a urine sample, which meant putting a straight catheter in to get a clean catch of urine. I felt like my baby was being tortured, and I felt like a horrible parent, but I didn't know what else to do. I wanted to make sure there wasn't something serious going on with him. Well ,to top it all off, the doctor wanted to do the Lumbar punture ( A needle is stuck in his back and cerebrospinal fluid is aspirated out). This was done to test for Meningitis. After a few hours of being in the ER (we were there until 1:30 am) They concluded that he DOESN'T have Meningitis, and his urine looked good. The only thing that we are still waiting for are the blood cultures, which can take a couple days to come back. Now it's 2 days later, and Cannon is still a little sick, but not nearly as bad as he was. Now I feel like I put him through all that torture for nothing. Was I being a paranoid parent? Should I have just kept him home and not taken him to the doctors in the first place? Kevin thinks it was just his teething, but I still don't think that would cause that high of a fever, and to cause him to act that way. I'm new at this parenting thing so I don't know. I'm just glad that he's doing a lot better.
