Hi There !!
Read through your prob. hope you continue the calf exs. what you can do best is lye down against a wall .. place your heel on the wall , let your hip and knee be bent 90dergrees each (90-90 dergree position )now tug your toes in i.e., flex your ankle and try to push the wall with only your heel... it would be a great strengthening ...without putting much pressure on your toes ..
To releave your pain you can use contrast bath ( cold water and hot water alternate immertion of your painfull toes )
Hope that helps ,
all the best
