Sorry, I'm gonna be a little pissed at you but don't take it the wrong way.
If you really think you had appendicitis, then you seriously needed to go the doctor. You should of tell your parents about this if your underage. If you decided to the hospital to get yourself checked up instead of the doctor, that bill at the hospital will cost you more then a doctor's visit. Most appendicitis starts at the lower right quadrant or basically the bottom right area of your abdomen. The pain moves close to the belly button with sharp pains. If things get worse you will get a fever because infections have already taken place and your appendix could possibly have a leak, leaking out all the crap that's in your intenstines. Don't think it's funny but it gets worse because the infection can't be contain and your white blood cell count is going to high as hell since they are trying their best to fight off the infection. Then when it's too late, you'll pass out like your friend and you could be dead on the spot. I can't believe you would spend your time posting here rather than go on google, finding out if you have the symptoms, and/or going to the doctor. If you did die, then tough luck for you for wasting time on this forum.
You don't need an ultrasound to figure out if you have appendicitis. What the doctor would've have done was press on the lower right quadrant for signs of pain and they will ask you if had a fever at the moment or recently. If there was no serious pain, they'll get a bloodwork to see if you have elevated white blood cell count. If there was pain after pressing, then they will refer you to get a CAT scan right away. Which you have to wait about 2-3 hours drinking a contrast medium fluid so that they can properly see what goes on in your intenstines. If they noticed the appendix being imflammed, then you'll be admitted to the hospital right away.
I thought I had appendicitis back then. I went to the doctor right away about it. He immediately refer me to get a CAT scan. I had to drink that constrast medium for hours and waited. Turns out I was fine. But the bill was around $200+ because of the CAT scan.
Lucky thing you got a swollen lymph node and hope it's not cancerous. You should wonder how you got that. It's also kind of strange to why it's on the lower right side. There are lymph nodes hanging around the intestines and their job is fight off infections by bringing the viral or bacteria infection to the node and to destroy it. The appendix is almost like a lymph node or it's main function is not currently known. I don't think you got this from your friend, but you could've ate something bad or you took some physical trauma to that area. You got lymph nodes everywhere, like your tonsils. They get swollen too, if they get infected and usually those things get excise. Ever wonder why women so easily get breast cancer? Their breasts are filled with lymph nodes to prevent the milk from carrying any infections to the baby.
it can be compared to getting 300 x-ray pictures at once
