Pain in left groin area, sole and ankle.

I'm suffering from left side groin pain which was very sever in 1-2 months of the beginning, now its mild. This pain is needle like which radiates to sole of leg (both), used to radiate in left hip too (not now) & recently in ankle(both). I saw gynecologist, orthopaedic but none helped, I got an x-ray done which was normal, my thyroid & sugar were normal too but I've high Vitamin D3 deficiency to which doctors said could be the possible reason but I'm doubtful. Also, one very important thing is I suffered from UTI in April after which this started. And also this pain in groin area & especially in legs gets triggered when my uterus is full. Until I use loo & empty my bladder it'll just get worse. What is the connection here, also what should I do about it? Please help. I'm just 19 & it's very annoying & uncomfortable. Thank you in advance. Btw I've been facing this issue from beginning of May but wasn't able to seek immediate medical help due to Corona.
