shortness of breath for days followed by a alot of stress..with palpitations

I have been having shortness of breath not heavy breath but always needing to take deep breaths. More conscious i guess of my need to breathe deep more often. During these episodes of breathlessness and nausia I dont have chest pain. Mabe a pinch or two in the chest area that are quick pinches. I am not hyperventilating. Its just a lack of oxygen! Not a bad lack.. I can still maintain my daily life..it is just causing me alot of anxiety. I am swollowing alot more too. Like something is in my throat. Liquid. Comming up?? I am not as hungry duriing this. Oh btw this has happened 3 times to me ever. The last one i ended up in the er with chest pain..nausia and dissyness. It lasted 24 hours or less. Everything came out as anxiety. EKG...blood work,,blood pressure etc. I dont know im just always needing to mostly ketch my breath,,I just had a baby..she is 7 months old..I dont know if this has to do with hormones? I am 34 mabe pre menopause,,hormones high etc? I am just tired of not knowing whats wrong??? Anxiety? Angina? Yes when its at its worst i get really breathless when trying to talk, walk, getting up from sitting. Would anxiety cause that? Also Alot of stress has always brought this eppisode on. Then it seems to last a couple of days then dissapering completly. ???????????????

I had palpitations while pregnant,,,,baby had a pericardial effusion..that resolved itself. Due to our well watter...huummmmm? Oh a few weeks ago my 12 year old daughter was sitting across from me and said MOM your eye!!! I got up and looke in the mirror. My right eye was stuck wide open and the left was droopy. this was happening and i didnt know it! I was under ALOT of stress that day!!!! It resolved within an hour after taking a lorasapam...!!!!!!!!!!!! CRAZYYYY! I know!
