Thank you for the query.
Blood is a very good foundation for bacteria to grow. So almost every heamatoma gets infected sooner or later and turns into an abscess
. Moreover, such foot swelling impedes blood flow through the arteries and veins resulting with muscles ischaemia. Such compressed veins do also get clotted and result with veins thrombosis
. That is why such swelling might be very dangerous.
Some part of such swelling needs to be incised and if possible heamatoma evacuated. Such incisions
gives more space for surrounding tissues so the blood can flow freely.
So if you find this foot getting more painful, skin gets more tense, you should visit a surgeon.
Anti inflammatory patch is good as well as foot elevation. However bandage can give more pressure and make it worst.
Hope this will help.
