Pain in left groin Down leg

Hello 

I’m freakin out I’m not sure what causes this but i could be 2 things the first one my period/ menses suppose to come today and yesterday I did some kick boxing and I’m sitting here and I got up and this pain on my left side lower groin cramp/dull/muscle pain just creep up on me on my leg . And is causing me heart rate and ansiety . I was sent to GYN due to a possible pelvic congestion syndrome.  

Have anyone has this? 

I exercise frequently and get the same ache, especially if I squat or go for a run. I have had all the tests, uterine biopsies etc all clear. I think its just due to imbalance of hormones so try not too worry too much

You know that after 30 minutes the pain went away just like that and I’m glad I didn’t rush to the Er. I was crazy mixture of premenstrual cramps , growing pain down the leg all in once and my period hasn’t show up. Thanks for listening and I love this forum it keep me sane from this journey we are all experience
