<s>[INST] I am 29 weeks pregnant and I have very intense lower back pain, low pelvic pain, spots in my vision that look like tiny fruit flies flying around, and after not having nausea since the first trimester I am very nauseous today. (there was protein in my urine my last urine test and my BP was in the normal range but slightly elevated to what it normally is for me) [/INST] Hello, Thanks for your query. Back pain in last trimester of pregnancy is not a pathological pain. I5 occurs due to change in center of gravity of body. As there is a fetus in abdominal cavity mother has to lean backward to maintain body posture. It alters normal spinal angle which is the main cause for pain. It will get resolved after delivery. You need bed rest till delivery. Avoid medications as much as possible. I do hope that you have found something helpful, and I will be glad to answer any further query. Take care </s>
