Both of my arms hurt when i touch them like when i put a lot of pressure on them they hurt...im 13 years old...is this bone cancer? my arm is not red sore or swollen it looks normal but i was just wondering.
they only hurt when i put pressure on thme they dont hurt at all when im not putting pressure on them and they only hurt in a certain spot when i put pressure on them they dont hurt anywhere else but in this 1 spot?
Oh yeah and i worked out a couple weeks ago

I have little lumps just under the skin all over my arms and upper legs. I thought it was cancer too, but turned out to be lipomas. Just ask your doctor or even the school nurse.
