Is My Sciatica Nerve Inflamed After A Miscarriage?

hello. i had a missed miscarriage 2 mths ago, about 2 wks before my body released the fetus i started feeling the nurves in my left leg getting painful and now 2 mths later it is still hurting well a sticking feeling and sometimes my leg feels hot another time cold and it gets more intense just before and during the first 3 days of my period( i have had 2 normal periods since my mc) could my sciatica nerve be inflamed? and could that have been the cause of my mc?
