Given this appears to be a chronic inflammatory condition and the "crunching" sound your hearing would indicate this. An initial approach would be to follow a principle of rice,rest and facial strecthing one stretch to try is lye on your back hips to 90, knees straight and dorsiflex the ankle and much as possible.
Assuming this doesn't make a difference it would be wise to continue your self-massage with golf's balls and the like whilst seeking the assistance of a qualified myotherapist or physiotherapist who is qualified in myofacial release, cupping and dry needling which would adequately address the plantar soreness.
As for the anterior ankle pain if this occuring at this base of the shin (tibia) you may require some joint mobilisations to improve the mobility and ROM of the ankle.
Reducing tension in the calves (gastroc and soleus) may also help
Worst Case scernerio your may have an anterior bone spur or a bone spur on the inferior side of the calcaneal (heel) bone. scans would confirm this
Hope this assists you
