I have so many symptoms.first, I have high blood pressure,,,then around 12:30 it drops way down, sometimes as low as 78 over 60,,, then again it will go up. I also have a balance problem. I can hardly walk without a cane or my husbad s ar. I am 78 years old. I just had a stress test and it came out fine. I have restless leg and numbness in my feet. Sometimes I have tremors right before drifting off to sleep. Do you have any idea what is going on?
