Now there is a painful lump there that was there with the bruise and never went away and it still very painful this is now 3 months from the dog craziness [/INST] Hi, Dear,thanks for query to Chat Doctor, from you for your lumps on leg after the injurious attack from your pet dog.1-I studied your query in depth.2-In my opinion, these painful lumps on the leg are the fibrosis healed up wounds with nerve fiber entangled in it.2-a-The bruised area went in to cellulitis, which got healed with entangled nerve fiber in it. That why you still have a painful lump at the site of the dog bruised bite.3-I would advise-you to go to ER Surgeon-who would do-Excision of the Scarred painful lumpy are-with biopsy-for this painful lump, the biopsy would prove the nerve fiber entanglement in it.4-Hope you got the answer you needed.5-Wellcome for more query to Chat Doctor. </s>
