Started lifting again after a 3-4 month break. I noticed today that from beginning to end I was feeling moderately winded. Like I was breathing fine but felt like I wasn t getting enough oxygen or something. Didn t feel dizzy but I did feel a bit cloudy. This happened last time I lifted but managed to become more sporadic the more i worked out, where I would have great days and bad days. Did some research on pulmonary hypertentison, not sure if that s the culprit. I just turned 23, I weigh 125lbs, I ve always been mostly active, eat plenty of fruits and veggies. Was diagnosed with allergy induced asthma last year, but during these breathing episodes I m not wheezing at all. Just increased heart rate and the feeling that I m breathing fine just not getting the oxygen. Any ideas? Thanks in advance
