Replying to Calf pain

whenever i do an ollie or anything where i’m leaning back on my tails, there’s this pain in the right back of my right calf that runs in an imaginary line up about 3/4 of my calf. same spot on my left, so left back of my left calf, but it’s not as bad, probably because i’m right hand and right foot dominant.

i doubt this is normal, so there must be something i’m either doing wrong or something that needs to be fixed. it feels like there’s a bit of space between the top of the boot cuff and my shin when i lean back, but the bottom half of my shin is still touching the boot. do i need to make some sort of boot modification(s) to fix this, if that’s the reason behind the pain?
