Hi,Dear thanks for the query to HCM virtual clinic.
I studied your query in full details updated from you.I understood your health concerns.
Based on your query data, In my opinion ,Dear You seem to suffer from
Retrocalcaneal Tendo Achilles or Ankle
bursitis.
and is caused by improper cushioning of shoes/ and could be associated with defects in plantar arches and needs to be investigated and treated from a podistrian ortho doctor.
X-ray and USG study would fix the cause of this painful bump behind the heel.
Hope this reply would help you to evaluate your case and treat it with your doctors in time to come.
Hope this would resolve your query and worry and
Anxiety accompanied with it.
Welcome for any further query in this regard to ME.I would love to help you out.
