What Causes Low Blood Sugar Levels, Severe Ear Infection And Blurry Vision?

My blood pressure was 139 over 59 at the Dr s today. I have been showing signs of low blood sugar as well. My norm blood pressure is usually about 95 over 60. He didn t seem concerned, since I have a very bad ear infection and he said could be the reason. Also my right eye (same side as ear infection) is very blurry. I feel pressure behind it and was only able to see top line of eye chart. He then referred me to opthamologist, who I will be seeing tomorrow. Is there reason for concern with my blood pressure? I am also in remission from Thyroid Cancer which spread to lymph nodes. Thanks for any information.
