Hello- My name is Martin I am 16 years of age & about a month ago I discovered a bump on my left clavicle (collar bone) & thought it was nothing because it just felt like bone & did not move. But since then from time to time it does give me mild pain & feels like that area is very tight. I told myself if it did not go away by the 16th I would ask my parents to take me to the doctors to see what it could be. I am very nervous to find out what it could be. I have an appointment Thursday. Cancer always comes to mind & I know it could be other things but I do worry a lot. If anyone is having or has had something like this happen it would be greatly appreciated if you would share your experiences. Thank you!
