One whole day I couldn't breath properly.had short of breath. Also felt very congested around chest like crushing from front and back.could not sleep with ease.doubted could be some gastric issue and took a rantac pill still had trouble the whole night.somehow slept erly in the morning and felt ok. This happened two days back. Even now I'm feeling little hard to breathe normally. Should go consult any specialist. If so whom. Please suggest otherwise.
