I have been having severe lower back pain for a few days now, it gets worse at night and often wakes me up. Ibuprofen and heating pad slightly helps but its still almost impossible to go back to bed after. When these episodes occur I also experience shortness of breath, like the air isn't being absorbed by my lungs. I've also felt nausea and stomach aches and what feels like trapped gas. I had a UTI a few weeks ago, but it seemed to resolve itself after drinking water and some at home treatments
