Are you having trouble breathing? Do you have a fever? Are you asmatic? It could be an attack. If so go to the ER or call a health line that could get you in touch wth a nurse.
OH have you been lying around and not moving around for awhile? I am no Doctor or Nurse but I have had a P.E. which is blood clots i my lungs and it felt some thing like you said.
If that is the case take a baby aspirin then go to the ER or call 911 for an ambulance tell them what is happening if by chance it is a clot you need to be in a hospital. If it were to move it could kill you or cause brain damage.
Praying for you
