Ache on this part ( image attached) Do?

So i dance once every 2-3 days, i do stretching almost regularly (i used to be a regular dancer a year back and hence i have good posture and flexibility) Since two months i guess , sometimes during my dance when it was a bit too strong even for a few mins, i would get pain in this area( see picture) , and it would give a shooting pain for a second when i would do cat pose ( a pose where we slouch our back) The area would be numb and this pain would shoot for a sec on some specific movement but it subsides the next day until i dance intensely again, it would trigger again and same cycle So I did not dance regularly , gave some days of relief too but still it would trigger some time Now it's been 2 months ,the pain triggers when i dance just a bit intensely, it is like a  pain that shoots sharp for a few sec when I do slouching movement. It still subsides in a day but now i am concerned what if it becomes chronic that everytime i dance intensely? What to do? Pls help
