Small bone chip in the elbow?

How do I know if the bump on my arm is a bone chip or bone cyst?

• so three days ago I accidentally slammed my forearm on the edge of my table at about a 45 degree angle. today I noticed this bump where I hit my arm. I asked my dad and he said it might be a bone cyst or a bone chip which really scared me. I looked these up and I got really worried. i was also kinda touching it and felt this thing move on my arm which made me think it actuaaly is a bone chip... please help I super scared.... also do you think I should possibly see a doctor??? ps: if u have had anything like this tell me what you did for it!!! thank you so much!!

• Answer:

  See a doctor right away sometimes cysts can wear away bone and a bone chip would also be bad so see a doctor. Just to warn you they will probably treat it like a fracture and give you a cast especially if the cyst was slowly wearing it away. My guess is its probably a chip but just to make sure see a bone doctor.
