<s>[INST] I am 27 weeks pregnant and I have a severe pain in my upper back. Some spot between my 5th and 6th rib. on the Left side. It s rather deep and hurts when I take deep breaths stand sit or lay down. The baby is kicking and moving around just fine as usual. It started the day before today. It has not lessened. Most things I read say when your rpegnant this is normal but the pain is rather intense. On a scale from 1-10 i d place it at an 8 when moving around. [/INST] Hello Welcome to Chat Doctor forum The pain can be due to acidity or gastric esophageal reflux which is very common in pregnancy for which you should avoid spicy food and Chat Doctor. Another cause can be pressure of baby on diaphragm, and it can be muscular pain also. Anxiety and lack of sleep also causes similar pain. It is better to consult your obstetrician for further evaluation. Best wishes and take care </s>
