I've had those shooting pains in my inner thighs here and there, too. They can be strong and alarming. This pubic symphysis thing is just a crazy, aching, throbbing type of pain though. It's like one person picked up one of my legs and another picked up the other and then the ran in opposite directions pulling them as hard as they could - 'crack'. As icky as that is to visualize, it completely describes what one would think the resulting feeling would be. In my case, the person on the left was the strongest (since it's the most pronounced there even though it's a central type of pain).
That hot rice sock did wonders yesterday...but I'm now back to hobbling again today. I guess my parents will just have to arrive to a less than clean house. And working out sure isn't happening (making me feel like a bum - I hate that!)... If this isn't a good lesson in 'letting go'...I don't know what is?
