I am feeling very hot then very cold, alternating for hours, and also lower back pain. I was just curious if there is something wrong that I am unaware of. I have rheumatoid arthritis, diabetes, and I am on several mental health medications. I just tested my blood sugar and it was 139, and my blood pressure is 155/109, pulse 96. I have had trouble with high blood pressure recently but stopped the medication because it got lower. I believe the high blood pressure right now is due to being upset, and feeling bad.
