I am 25 weeks pregnant now and had been using ameltz yoko yoko. But last night i put quite a lot than usual at the backside of my body because i fell a terrible back pain. Suddenly my tummy feel so hot and i started to feel the pain at my stomach. I feel my stomach like bloated and difficult to breath. I hardly say a word and hardly need oxigen. I couldn't move but i tried my best. Everything seems helpless. So my husband brought me to the nearby emergency ward and after 30 minutes the pain had gone and i can breathe like normal. The emergency doctor gave me trauma jab. After that i was shivering because i feel so traumatised with what had just happened to me. Luckily my baby heartbeat is normal. So my advise to you is.. Better avoid it. Or if you really need it maybe just use baby oil or use medicated patch. But through my searches, some doctor says it is ok to apply ameltz yoko2. It is better for you to get confirmation from the doctor. But for me, i swear i wont use it again after what had happened to me last night.
