Leg/Foot Massage in 4th Month Pregnancy.

Hello Doc, My wife has completed 1st Trimester & is in 4th Month. She has started to feel leg & foot pains/cramps mostly from evening till early morning. Causing a lot of discomfort to her. She keeps pillows under her feet at night & also taking calcium/vitamin supplements. She walks 2-3k steps daily. No history of DVT or Diabetes or hypertension. She wanted to have regular foot & leg Massage to get relief. My questions - 1) Is it fine to get professional leg massage regularly in pregnancy? As masseurs hands are rough & they do massage strongly. 2) Have read there are accupressure points on foot & legs that are needed to be avoided to avoid pains & contractions. So is it advisable to get the massage done? 3) If yes then how regularly can the massage be done? Everyday or once-twice in a week? 4) Anything else to be taken care of. Thank you & looking forward to your responses.
