I am a 23 year Old pregnant female. I have had strange symptoms the past 5 months now and still now answers. I am very concerned about this. I have had an MRI done in my head due to intense sharp pains on top of my head. My results came back normal. I am in the process of having my heart looked into and will receive results this Friday from my echo stress test I had done. I hope everything comes back clear. Due to all the strange symptoms I have been having this seems to be heart related. My symptoms include: chest tightness, feeling heavy, hard to breath, left arm pain, back pain, dizziness, fuzzy feeling in left arm and foot, feeling severely unsteady while walking and sitting, left arm pain seems to ease while sitting, wheezing, hazy vision, pain in left side of neck, pain in between shoulder blades, heart palpitations, am so scared that this is heart related. I have two small children at home and worried something bad is going to happen while I am home alone with them. These are not normal pregnancy symptoms. Please, please,please help and tell me this is all anxiety although I never feel anxious or stressed. Not all my symptoms last all day but most of them do.
