Feeling something moving like maybe bubbles in my lower back when i take a deep breathe. it dont hurt my spo2 level and heart rate are normal. i had just ate dinner and was walking back to the car and got kinda short winded. what could this be?

I assume you're a nonsmoker. Do you have a cough,wheeze,chest discomfort with a deep breath? Although we don't recommend exertion.immediately after a meal, you shouldn't get short of breath just walking to your auto. I'm concerned about a pulmonary problem even with a good O2 sat. Anemia is another possibility. I recommend getting examined by your MD & having appropriate testing if symptoms persi
