<s>[INST] I recently was rea ended by a vehicle from the side. I started my first therapy for a stiff neck and lower back pain. I have two large lumps that formed overnight on my lower spine area near thebottom approximately horizontal with mith my hip bone. The lumps are on both sides of the spine, and are red. The lumps are hard, but no pain coming from them.. [/INST] HI, Dear,Thanks for the query to Chat Doctor.1-I have studied your query in depth.2-DEar,IN my opinion, the bilateral low spinal painless lumps formed overnight after the vehicle trauma, are mostly due to the sacroiliac arthritis -post trauma-with indicated tissue lumps.3-Other reasons could be traumatic hematoma?which needs to be fixed.4-I would advise orthopedic surgeons opinion, for more detailed history to come to the cause of these red painless lumps.4-a-Treatments-would be decided by an ortho-Surgeon-for the lumps below the toe, after S-I joints X-ray studies in various planes.5-Hope this would solve your query to your satisfaction.5-Wellcome for more queries to me On Chat Doctor.6-Thnks once again for your inquisitive query. Have a Good Day.!! </s>
