your blood pressure is wrong. you need to see a doctor right away. You could have a fainting spell that could hurt you very seriously, like hitting your head on a surface so hard that you could actually die, i know somone that did die hitting her head on the tub. Your blood delivers oxygen to your brain and your extremities. Something tells me that your faulty blood pressure may have an effect on your blood sugar level, which can mess you up as well. Make sure to get to your doc. right away. Best to keep a list of your meds in your purse in case of a fainting spell you can't wake up from occurs so that ems will know quickly what you are dealing with. Keep a bottle of water on you and a protein bar as well. Dehydration and low blood sugar are not good and could also lead to fainting. The protein will help if you are anemic. good luck.
I am not a heart doc by any means, however, I would go in. It was way easier to check and make sure this is normal then to find out later that it was warning signs. Also, do you have insurance? On the back of your card should be a nurse hotline that you can call and talk to a nurse to get better information. If you are insurance free then go online and try googling a free nurse line. I am so sorry that I am not more of a help, I know what it is like to feel completely off and be a bit shaken about it. My thoughts are headed your way sweet heart!
Sounds like your bp is way too low. Check with your doctor. Your circulation is not good. You might want to try some very moderate exercise - just raising your arms a couple of times and your legs before getting out of bed. Be careful when you get up from a sitting position. - I have MVP too and find that taking CoQ10 makes the heart stronger. - You say you have no appetite, perhaps a milk shake or an instant breakfast can help you with this.
