Shin conditioning idea's

[dazak]

Hey all, If I hit a heavy bag too hard low down alot or kick pads i'll get a pain in my shins, It dosn't swell up and I assume its just because they arent conditioned enough - however I've been doing muay thai for a good few months and i've taken a month break to heal but the same issue arrises after a couple sessions back to back. is there any proven conditioning techniques besides kicking the bags and pads, is the stick roll worth a try? Thanks
