Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems that there has been inury to the soft tissues of the nail bed and theer might be some detachment of the nail bed from nail plate and due to it there is swelling and bruising is due to
injury to blood vessels leading to spillage of blood into soft tissues leading to bruising as well as there can also be
hematoma formation..
You can do cool compresses over the area..
Take anti inflammatory painkiller like
Ibuprofen..
You can also apply a combination of
steroid and antibiotic ointment over the area..
In case if pain and swelling exaggearates you can
consult a General Surgeon and get evaluated and he can look for nail plate detachment as well as if some portion of nail has detached from nail bed he can remove it under local anaesthesia and do an antiseptic dressing and bandage it followed by antibiotics and painkillers..
You should also avoid further injury to the toe as it can commonly get bumped to prevent further injury..
Hope this information helps..
Thanks and regards.
