@ral In the PT clinic I would have not just stretch the calf, but the soleus and most importantly mobilize the fascia on the bottom or plantar side of your foot.
Put the sole of your foot on a 2" step then do what looks like a calf stretch but you drive your knee over your toe with your knee bent.
In addition freeze some water bottles and roll your bare foot on it till numb a couple of times a day.
Lastly tape two tennis balls together- use coban. You can also do some really good fascia mobilizations with the balls as well!
I need to have my own beer fund part of this forum for free PT advice!
