Wow - check ups every 6 months - that is really good. I don't put tiger balm on the actual scars themselves though - I am not that brave! I use Bio Oil on them religiously every night. Tiger balm has quite natural ingredients in it - menthol, camphor, clove and cassia oil, peppermint and cajuput oil (whatever that my be) so it can't be that bad - I would never put it on broken skin. Are you still on some form of hormone therapy - that may be causing pain as well. I have permission to come off Letrozole for 2 weeks as I had awful backache, within 2 tablets of stopping the pain had gone, I have had so much energy since then, but due to see my surgeon this week for an alternative for the next 4.5 years. This long weekend I have been drinking lots of iced water to try to help - but find it hard to drink that much when I am at work. Am so busy during the day that I think I only notice the symptoms at night, and also bed is warmer too. Let me know how you get on at the check up.
