I've been in martial arts since I was six, but I recently got to the point were I just relied on my hands, ive been this way about two years, and I started studying kiccs again so I could use more of my body, and adapt to more circumstances. However I noticed that when i do a high roundhouse a shooting pain goes through both of my groin muscles, now I can do the splits four inches from the ground, and I do the butterfly, and the frog before I practice so I dont think its an issue with my flexability. I can do side kiccs, and hook kicks at head level with no problem. The only things I think this can be is teqnique, or some kind of groin injury, but I cant seem to isolate the problem. Anybody have any suggestions let me know, cause Im broke, and cant afford an instructor right now.
