Hi..
Welcome to HEALTHCARE MAGIC.
I have gone through your query and can understand your concerns..
As per your complain it seems that due to hitting with a metal bar there has been
soft tissue injury and due to injury there has been inflammation and swelling due to accumulation of inflammatory exudate and cells at the injury site..
There also seems to be ruptured blood vessels leading to bruising and formation of a
Hematoma..
The movable gel like lump seems to be a Hematoma and is due to accumulation of blood from ruptured blood vessels..
I would suggest you that you need not to worry about it as it will resolve gradually..
You can do alternate warm and cool compresses over the lump..
You can also give him anti-inflammatory painkillers like
Ibuprofen.
In case if there is pain numbing gel containing Lignocaine can also be advised..
You can also apply
Heparin gel over the area as it will help in faster disruption of the hematoma as well as bruising..
Hope this information helps..
Thanks and regards.
