I suffered terribly from sinus headaches, just as I thought I'd got over my morning sickness! and of course couldn't take the nurofen I knew would have fixed it. I often get inflamed sinuses this time of year and nurofen works wonders. But of course all I could take was panadol, and it wasn't working. The only relief I could get was from a cold flannel on my forehead, or over my eyes & nose, or at the back of my neck.

I think it's safe to use essential oils in a burner with about half the amount you'd usually use (don't quote me tho!!) as opposed to putting it on your skin. Perhaps a little lavender in the air will help. I didn't get around to trying it as the flannel helped me get some sleep.

Try to keep your fluids up tho, coz dehydration can cause/aggravate headaches.

Take care, I hope it eases up for you soon.
