Hi, thanks for the query to H.C.M. Forum.
Diaformin is anti-diabetic tablet, hence you are using this tablet for diabetes
Your's main query is that not taking of diaformin and ankle ache related to each other.
I would like to "YES", if pain is due to obesity or diabetes.
Sometimes when glucose
level increases in body , patients starts feeling pain in muscles ( calf muscles) .
Tendon of calf muscle related to ankle joint so in diabetic ( sugar level increased due to diaformin absence) patient feels pain around ankle joint.
One more thing is to remember for you that if this pain recur in spite of diafromin use than consult a physician and his opinion must be.
Control your diabetes in any condition.
Good luck Dr. HET
