Hai mama! 36 weeks dah, memang banyak physical demands kat badan. Tapi sebab ni involve multiple symptoms dan you're at a critical stage of pregnancy, please go see your doctor or midwife asap , jangan tahan-tahan ye, better safe than sorry. Kebas tangan boleh jadi carpal tunnel (common masa pregnant), tapi combined dengan lower abdominal and lower back pain, kena check proper dengan doctor aje. A few of my mum friends ada similar symptoms dekat end of pregnancy, but each situation berbeda. Hopefully semua okay lang, but get it checked ASAP. Take care!
