In the last few weeks i have developed a pain in my right heel. Its not painfull all the time. When i start my run i can feel it but after about a mile into my run it wears off completly. I notice after my run it is painfull to touch like a bruise but there is nothing no lump or anything. Its the same in the morning when i wake up but by the time i go to work its gone. Some members of my running club say it could be the plantar fascia , has anyone got any idea what my problem could be and remedy for it .
