I'm 37 weeks pregnant and im feeling sharp shooting pains in my inner thighs shooting up to my vagina. I can barely stand. What should I do?

Try. An OB girdle to support the weight of your abdomen to help alleviate this pain. Round ligament pain can be quite severe. Talk to your ob.
Round Ligament. It could be from the round ligament of the uterus stretching as the uterus expands. Most women describe it as a sharp or tugging pain radiating to the labia. Try tylenol (acetaminophen) for the discomfort and consult your OB so you can be properly evaluated. Avoid any NSAID drugs (like ibuprofen) unless your OB says its ok.
