My mother has experience symptoms: weakness of the left leg, unable to lift up the left arm, blur vision on one of the eye, speech OK but not clear a few words, and not clear in the memory (she does not remember where she is, in her room or other room). Is this a sign of stroke? She is 83 y.o. and has fluctuate blood pressure, taking pills as needed. She takes her blood pressure daily. The symptoms have occured since yesterday, should she wait until tomorrow morning to go to Urgent Care? Her PCP told her to wait until she getting worse then go to ER. Is that the right advise? Please help.
