Welcome here on HCM.
I am trying to help you and think I will be able to do so.
Home cares you can do are
Sleep with foot raised as high as possible.
Complete bed rest
for 1 to 2 wks.
Over the counter analgesic
as you need.
Ice packs fomentation, 15 minutes at a time, five to six times a day.
If these do not solve your problem, than contact your GP, for clinical examination and some investigations to be done.
Get well soon.
