Mr. lybrate-user, Thanks for the query.
It is better to chek her fasting, PP blood glucose levels and HbA1c%, that will give a clear idea if she has diabetes
. Fasting 114 mg is suggestive of pre-diabetes. Pain
shoulder and difficulty in movements may be due to a condition called frozen shoulder
. Better to get above tests and then see an orthopedic. Diabetes is known to cause this condition, particularly when not in good control. Thanks.
