For the past week or so I have been experiencing chest pain when I wake up. I usually sleep on my side so I thought it might be cause of that but now, I m not so sure. I am a 23 year old female, healthy, non smoker. I ve also experienced my right arm becoming numb in the middle of the night but its not the side that I am sleeping on so it is strange that that arm would experience falling asleep feeling . I have not been sleeping well either, I ve been waking up regularly throughout the night for no apparent reasons. This morning was the worst chest pain, it hurt extra to breath in deeply as well. The pain subsided as I woke up and after a shower and my regular morning routine. It s still a little bit there, I m just not sure if it s something I should be concerned about and see a doctor, or if its just the way I ve been sleeping. Thank you.
