Hi,
Thanks for posting your query.
You are prone to
arthritis as you are
overweight but present pain above ankle is not related with arthritis.
This may be due to low calcium, deficiency of 1,25 dihydroxy
cholecalciferol.
You should consult with internal medicine specialist/
neurologist and should go for thorough check up.
You should go for x ray of affected limb, nerve conduction studies and color doppler of affected limb.
You should also take coenzyme Q, vitamin E and calcium preparation.
You should also reduce your weight for better living.
You should also go for serum calcium, serum 1,25 dihydroxy cholecalciferol level.
take care,
Dr. Mayank Bhargava
