My mother (age 52 yrs) being a diabetic patient use to take medicines (tablets) for it since a long time and subsequently shifted to insulin injections shots twice a day of 12 mm in morning and 10 mm in evening However, now she has stopped taking insulin since last 2-3 months (mainly due to pain caused by the injections) and shifted back to her earlier tablets and also try ayurvedic methods like chewing insulin plant leaves and likewise. Though she is not regular with these homemade ayurvedic measures, her diabetics has been little down now from 300-350 level (when she use to take insulin injections) to current 250 level. Now from last 2-3 weeks she is having pain in her right knee which is getting severe resulting in sleepless nights. Doctors referral has ruled out any fracture and have simply advised her to loose some weight (though her weight is actually average) and apply massage oil on it. Need some concrete advice to subside her pain. Thanks in advance.
