Hello and welcome to HCM.
Sorry to know about your accident.
It seems that you have got
deep vein thrombosis as a result of long immobilization you had because of fracture foot.The pain can also be due to prolonged immobility of your foot in splint.
If I were your treating doctor,I recommend,
-Advice investigation like Doppler scan of legs for blood circulation
-Applying compression bandage on your leg
-Do frequent flexion,extension,rotational movements at ankle joint.Avoid standing for long.
- Cold compression can be applied to aching area.
-Sleep or sit with your leg elevated
-Take
calcium supplement.Avoid pain killers like
ibuprofen -Report immediately if you face symptoms like
shortness of breath or
chest pain.
Hope this information helps
Thanks and regards.
