You will be sent for more xrays, possibly ctscan or mri, and possibly a bone scan if you have multiple locations. The best thing I can tell you is REMEMBER - benign bone lesions are very common and you can also continue to live life fully without surgery (unless you are having trouble). And they might also recommend a bone biopsy - but this is still very common. So try not to worry too much.
Also - remember that different doctors will call it different things - lesions, cysts, and tumors have all been used to describe benign bone lesions/cysts/tumors.
I would highly recommend an orthopedic specialist. Usually they will have their own xray machines (some even have their own mri machines) in-house and you don't have to wait on the results. Wishing you the best and let us know what happens.
