If you are a doctor, please answer the medical questions based on the patient's description.

### input:
I am a fifteen year old female. For about a week, I have been experiencing a sharp, kind of stabbing pain in my lower left abdomen (directly next to my hipbone) when I walk or do anything that involves moving my torso. I feel it when I extend my leg when taking a step and I end up walking differently to compensate for it. It becomes much more prominent immediately after I eat and if I don t eat for a few hours it s much less noticeable. The pain is very localized and in the exact same spot every time I feel it. I mentioned it to my dad when it started and I didn t talked about it to anyone again until today because I thought that it was going to go away. If anything, it feels worse now than before and I m scared to move or eat (I haven t stopped doing either); It s very uncomfortable and it feels very wrong. It sounds strange, but the best way for me to describe it is that it feels like one of my organs is out of place. I noticed a bit of swelling when I got home today, but there s none now and I don t know if it was real or if my nerves were getting to me (I did check a few times to confirm it, so it was probably legitimate). I only checked for it for the first time today, so I don t know if there has been any for in past week. I tried to ignore it, but I m scared now. I almost contacted my parents at work today so that I could ask them to take me to the hospital because I didn t know what to do. What do I do? What could it be?

### output:

Thank you for using Chat Doctor. It could be neurological or abdominal condition which needs clinical examination and if needed further tests like an ultrasound. If its neurological likely to be sciatica but do you've radiating pain in lower limb? If its abdominal could be an abscess for which fever would be present or is there a swelling in the groin which could be hernia. Please visit the hospital ER at the earliest so that it can be ascertained and treated.
