<s>[INST] I slipped on ice and fell on steps. I had a very large haematoma on my lower back but I still get a burning sensation every know and then.  The swelling has reduced considerably but not away. This happened in November.  I went to the hospital twice and then visited my doctor at end of Dec and he called a specialist.  They said on hindsight that they should have removed the blood at the time.  Just because of the stinging I wonder if I shd go back [/INST] Hello. Thanks for writing to us. After the fall, the hematoma that formed must have been compressing the nerves causing the burning sensation in the area. Most of the time such hematoma resolves spontaneously in 2-4 weeks with rest and hot fomentation. I hope this information has been both informative and helpful for you.
