I think I had something similar. Started hurting in December only recently has it stopped. For me the problem was tightness in calves and into my foot, when u did calf stretches I felt it pulling in the sore spot at back of heel. I did a lot of calf stretching, ankle mobilization (ankle rotation, pointing toes then pulling back towards the ankle, tilting foot from side to side) and rolled the underside of my foot/arch using a spiky massage ball.
I dunno if this will help. Exercises I did are things recommended for plantir fasciitis.
