Hello i am 17,

Recently about 2 weeks ago i noticed a small lump on my upper left testicle. I was very concerned about this. Then five days ago i felt an excruciating pain from what at first i believed came from my testicle, but it turned out when i properly looked and felt it it was from my inner thigh, there was a pain that went from my hip down to my thigh it hurt most when sitting down but whilst standing didn't hurt. After that it didn't hurt at all, but i am very worried and concerned for some reason.
