Thanks for the replies girls.

I did tell my physio that I was pregnant and that was the reason I wasn't taking any Nurofen or Voltaren so he knew this info before he applied the Tiger Balm and then recommended I keep using it while my knee was recovering??

I'm seeing him again in the morning so I'll speak to him about it then. He was saying his wife is a physio and she has had two babies so I'm sure she'll be familiar with what was safe to use in pregnancy. No doubt she would have mentioned to him if Tiger Balm was unsafe seeing it is the main thing he using in his practice apart from the usual physio gel??

Still I'll take your advice and be on the safe side. Might give my Dr a call and quiz her - have to speak to her anyway re. blood tests.

Thanks girls
