Hello fellow blenders! 

Has anyone of you experienced pain as I have? Night ago I woke up due to throbbing pain in my right foot. I did not get hurt recently, no hiking... only reason for it I found, is in overdoing lunges (But I did not do lunges day before pain started)The spot is painful to touch, while walking and while moving with thumbs. It is only painful on the back of the foot (on the picture)I have no idea what is going on.

it looks, that cooling helps to reduce the pain.

 Due to the Covid situation I would like to avoid going to see a doctor.  

Thanks for any idea
