The only time I have ever seen the plantaris cause problems, pain-wise, is when it ruptures. When a plantaris ruptures, it is often described as a rubber band like feel/sound or that someone hit them with a stick on the back of the leg. These generally resolve into being asymptomatic by 2-4 weeks post rupture.
Never heard, however, of the plantaris causing heel pain, but I suppose it is possible. Honestly, I don't think it is strong enough of a muscle to cause any significant pathology at the heel. However, I have seen it used for nice little tendon grafts for reinforcing Achilles tendon rupture repairs.
