Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain chronic pain
in heel can be due to causes like traumatic injury, Achilles Tendinitis
, Brusitis, Arthritis, gout,heel spur, heel pad wear,fibromyalgia
I would suggest you to consult an Orthopedician and get evaluated and a thorough clinical evaluation and investigations like X RAY, MRI SCAN and blood investigations can help in confirming the exact cause and treatment can be planned according to the cause confirmed..
You can be advised to take anti-inflammatory painkillers, steroids,cool compresses can help..
You can be advised to undergo physiotherapy
under supervision of a trained Physiotherapist..
You should wear less healed and proper fitting shoes..
Sound wave therapy can also be done for promoting healing..
Hope this information helps..
Thanks and regards.
