The pain is located where my achilles attatches to my heel on both sides of the tendon. my foot was casted for 3 months...with no relief.?

You may also need: Some form of physical therapy; antiinflammatory medication if you haven't already/ laser therapy--the pain relief kind--can be of help too. There does come a point where, if there is enough spurring, that surgery may be indicated.

Need to see Dr: You need to be reevaluated, at least a new x-ray maybe mri. I would recommend physical therapy, possible surgery depending on MRI finding.
