### input:
Hi my dad fell and theres a huge swelling in the middle of his back even covering the spine area - it is huge - bigger than my entire hand. I put ice on it but it seems to be getting bigger and bruising - theres no pain though. he has recently been quite ill with post shingles pain in right arm. he also had a catheter for over a month which caused infection and is also a dialysis patient - also has history of aneurism of the aorta. Hes quite a strong soldier. Very weak after the infection and post shingles. Always unsteady after dialysis. The huge lump on the spinal area after his fall is bothering me. The last time he fell I drove him to the ER coz he had trouble breathing and had a slight fit. Hes been in and out of high care and home for afew days but still weak and cant sleep. He forgets and tries to wake up out of the bed and falls......please tell me if I should worry about the lump on back or hang on till the morning for the doctor to see him. the lump is atleast 15cm long and 8cm wide.

### output:

Hi, dear thanks or the query. In my opinion this lump is definitely cause for worry and needs to be attended urgtly-STAT. It could be life endangering if you wait till moving. Shift him to nearby hospital. In my opinion could be post-traumatic hematoma. Still in view of the history of Cancer and dialysis and aneurysm of aorta, your fathers' case is critical due to the inbuilt risks to life in the event of the huge back swelling -post fall, though prima facie it is due to the post-traumatic hematoma-which is growing -which is the cause for worry. Thnks. Hope you would ugly shift to ER. Hope you got the right answer Welcome again. Take Care ugly by shifting your father to ER for further care.
