Hi,For the past couple of days, I've been experiencing and unusual ache/pain just at the top of my left leg where it meets the adbomen, sort of in the groove between. It's the type of sensation you get if you accidently knocked you're testicles, but no where near as bad as that would be. I don't notice it really when i'm standing up, walking, or laying down in certain positions. Only when i sit down mainly. Just feels uncomfortable. Sometimes feels like a bit of trapped wind sometimes, but I don't think it is because of where it is. Also feels like a lymfnode (a kind of swollen gland), as I have has those in my neck in the past. Has anyone else had this before? Do you think I should see someone about it? It's not bad, it's just noticable. What about cancer?I'm 16 by the way.
