Hi, thanks for writing to HCM.
It is very uncommon to have bruise
marks leftover even after 3 months of injury
as the maximum time by which they fade off is around 3-4 weeks. Anyway its not a matter of major concern.
Regarding you swollen ankles and feet, I think it is normal for your age after period of walk and prolonged standing and can be considered as "Physiological" dependent oedema.
If you are much worried and concerned , approach a vascular surgeon for evaluation. Hope this helps
