A lump near the shoulder could be an enlarged lymph node, an abscess, a cyst, a tumor, etc. I would recommend that you have Roscoe examined by a vet, especially since you have noticed a behavior change. The vet will do a thorough physical exam, and may want to collect a sample of cells from the lump to examine under the microscope. They may also recommend blood work or other diagnostics to see what could be going on.
