I haven't experienced anemia personally, but my mom has it. She has always had a fast pulse (so have I, but I'm not anemic). Besides being anemic, my mom also has diabetes (controlled by oral meds), osteoporosis, and GERD. She takes iron pills that make her reflux go crazy. Also, I'm not sure, but she may have had high blood pressure until it was controlled by meds. She does NOT have fibro.
I will ask her if she ever has (or has had) blurry vision. If she did, it was probably due to her high BP. I will definitely get back to you about this (but it may be a few days cause I'm moving this weekend). BTW-like most of us, I've seen many doctors who don't seem concerned about certain things, and then I find out that he or she should have been very concerned. My opinion is go with your gut, and if you feel a 2nd (or 3rd) opinion will help, then go for it. Remember, this is your life you're talking about!
Good luck with everything!
