Ac joint injury from fall. bump showing,went to a specialist and the xrays came out okay. he advised doing nothing? should i be concerned about bump

Probably not: Most people recover from AC joint separation in about 2 to 12 weeks without the need for surgery. However, your recovery may be slower if you have arthritis in your shoulder, damaged cartilage between your collarbone and your shoulder blade, or a severe shoulder separation.
