Hi..
I have gone through your query and can understand your concern..
As you have got hit over the shin there is
soft tissue injury and the injury leads to inflammation and small blood vessels gets ruptured and the blood spills in the soft tissues and forms a
HEMATOMA and bruising..
The hematoma at times gets encapsulated by inflammatory cells and overgrownfibrous tissue which are formed due to inflammation and thus there forms a hard lump.
Numbness can be due to damage to some nerve fibres or can also be due to inflammation.
You need not to worry as the lump takes a long time to resolve but I will definitely resolve slowly..
1. You should do alternate warm and cold packs over the lump for faster healing..
2. Apply
Heparin Gel as it c helps in faster disruption of hematoma..
3. To relieve pain if it is there you can take anti-inflammatory painkiller like
Ibuprofen..
In case if still there is no improvement consult a General Physician and get evaluated..
Hope this information helps..
Thanks and regards.
