Hay, ganyan din ako noong 7-8 months, ang sakit talaga especially pag nakatayo o natulog sa side, kaya please check with your OB agad, sciatica can get worse towards the end ng pregnancy at important i-manage properly para hindi ka mahirapan sa labor. A few of us tried prenatal massage at pelvic tilts, and honestly nakatulong, pero your doctor should really assess kung ano exactly ang pressing on your nerve para ma-guide ka ng tama.
