My grandma aged 75 approx have high BP and Sugar for the past 10 years. She is undergoing insulin for twice a day. For the past 1 month she is facing severe pain in her whole left hand. 3 weeks before heavy blood flow happened in her nose without pain. So we admitted in hospital and took treatment for 1 week. Now blow flow stops to come out from her nose, but pain in her hand still continues. Can you pls confirm why she is facing this issue and how can it be treated. Your reply can save her life.
