Hospital??

H

I am having terrible sharp pains when standing or walking, to the point I have to brace myself to stay up. However, when I sit down, it pretty much goes away. Do I go to the hospital?? I don’t think it seems normal to feel so uncomfortable while standing but don’t want to waste a trip to the hospital for no reason. It’s not like they’re contractions.. they are sharp pains in my pelvic area. Please give me some advice!!
