My 83 year old mother who has Alzheimer s , lives in a care home. She is being treated with hydromorphone, and Xarelto, for a DVT in her left leg. Her leg was/is blue and cold, and she also has developed numerous blisters some of which have burst and the skin peeled,. Her toes appear blue/black.....and we are awaiting a Dr. to come and see her as her GP is away on vacation since prescribing the above medications. She is now 4 days unseen, and 3days since the blisters appeared.
