I have a tight feeling in my chest and short of breath?

I have a tight feeling in my chest and short of breath. I’ve been having pain my chest and left shoulder and upper back as well. Sometimes I feel like I can’t move. And my arms feel weak. I’ve had nausea like I want to be sick all night. I don’t smoke or drink. I’ve had the pain two weeks but the shortness of breath and tightness in chest since yesterday. Thanks

Diagnosed with bronchitis 5 days ago, I feel short of breath and my heart starts racing?

51 yr old female diagnosed with bronchitis 5 days ago. Taking amoxicillin, tessalon perles, Proair inhaler and guiafenisen. No wheezing, chest xray was okay. Some dizziness but could be from sinus congestion. O2 sats are great during the day when up, moving and coughing. As soon as i lie down at night, drop to 96-97% but when I start to doze, i feel short of breath and my heart starts racing. O2 sat drops to 90%. Now I’m afraid to lie down and sleep.
