I'm a 23 year old female in generally good health. I do suffer from anxiety and iron deficiency anemia. Lately I have been feeling extremely nervous, a lot of muscle tesnion in my neck and head, slightly dizzy, tired and my blood pressure has been running slightly lower than normal. I usually range around 120/80 but lately it's been around 100-110/60-70. I've also been having a rapid heartbeat and a few palpitations. I don't know if this is due to the anemia or the anxiety or both. It makes me nervous just thinking about it. I've been taking iron tablets for the past few weeks. Is this something I should be worried about or could this be more of an anxiety thing. The main thing that really concerns be is the low BP, tiredness ,and slight dizziness. Any help would be great.
