I'm 24, female, slightly overweight but largely quite healthy. I've had no problems in years (I did have basal cell carcinoma 5 years ago, no recurrence since then) besides the normal head colds and the like, I've a very clean bill of health and just had my yearly checkup and blood work done two months ago.
For about 28 hours now, however, I've been experiencing a lot of pressure on my chest. With it came the feeling like my heart was pounding - I took my pulse and found it at 104 - my normal resting heart rate is 62-66. My fiance has a blood pressure machine for home use, and my BP was 94/64 (normally 115/77).
I had a lot of trouble sleeping because the chest pressure turns to pain when laying down.
I have taken my BP and pulse a few more times since then - my systolic BP is up some, but my diastolic continues to drop. 10 minutes ago, it was 104/54. My pulse rate is hovering around 80 - which is better than last night's count, but still high for me.
My doctor isn't open on weekends and the urgent care has 3 hour wait. I'm just looking for help or insight or whether I should really see a doctor at all.
