Severe Planter Fasciotomy

My husband was diagnosed with planter fasciatomy in Jan of this year. He had surgery March with very high hopes that this would fix his pain. We did not know at the time, that some of these surgeries for planter is not successful. Since then, he has had 3 cortisone shots. He works on his feet 12 hrs a night, he has dr made orthotics, and has a 2nd opinion. They both told him there was nothing else that could be done. He is still in constant pain every day and we don’t know what other options there are, ours drs are not being very helpful with this.
