Hi, Sherry! I don't think BP dropping is a symptom of fibro but it definitely is a symptom of something. I had that happen to me. I was on a diuretic and also Accupril for my blood pressure. I then lost weight. When I did, my blood pressure dropped dangerously low. When it was checked at the doctor's it was 60/32! They didn't know how I was even walking. I was taken off the diuretic but kept on the Accupril.
A few days later I bent over to get a pan out of the cupboard and got really dizzy and then I couldn't breathe! Now THAT frightened me. I was gasping for air and my daughter wanted to call 911 but I knew it was the blood pressure problem. So I just stopped the Accupril, too, and, since this happened on a Sunday of course, I called my doctor the next day and told him I stopped all blood pressure meds. He had me come in and my blood pressure was perfect...100/60...very similar to yours...with no medication. This happened five years ago and my blood pressure is great without any medication now. So, if you have lost weight or something else happened to help with your blood pressure, you just might not need the medication anymore.
I've had some dizziness occasionally. Sometimes when I get out of bed in the middle of the night, I feel like my body is slanting to the left. Don't know why that happens. Your vertigo could have been sinus that was affecting your inner ears. I'm not a doctor but that would be my guess, since it did clear up.
We all have varied symptoms with fibro. Pain is usually the hallmark of this illness, along with fatigue and cognitive memory problems. I didn't have memory problems right away but when they started I thought I was getting Alzheimer's! Nope, just fibo fog. I've had a lot of laughs over the years with things I have done, like trying to start my car with the key to my freezer. That's my favorite one! LOL And, of course, we can have fibro and other illnesses like arthritis. But, you can still have a full and enjoyable life in spite of fibro. I know because I have!
Don't hesitate to ask questions. I'm sure there will be plenty that will pop up. We are here to help you. Hope to hear more from you soon.
