My first port of call is the internet. I know everyone says don't, but there is good information out there if you stick to quality, trustworthy sites- I'm an information scientist so i know how to evaluate information carefully. The internet is great because you have instant access to a wealth of information and it's anonymous.
Also, I use the internet after diagnosis because they never tell you enough at the appointment. Usually a sentence or two but i really want to find out more, and read around it.
I also borrow LOTS of books and read online women's magazines from the public library - which can be helpful for more general advice on things like menopause and nutrition, self-help type books too occasionally, and info for other family members' issues - depression, anxiety. And I talk to family or friends, depending on the issue.
Money can be a barrier- you read about supplements being recommended- eg menopause or I have joint problems, but just can't afford them.
I had a shoulder problem and ended up paying to see a private physiotherapist because I knew i would have to wait months via NHS. I paid twice- once to get a diagnosis- once I had that information I could look up online for specific exercises- YouTube has brilliant videos which show you what to do. Plus one follow up appointment to check things were improving. It's fixed now- i'd still be waiting on the NHS- but I did it with a combination of private physio and finding info for myself on the internet.
It can be difficult to get a doctors appoint ment - and the idea of seeing the same GP twice in a row appears to be very outdated. i'm getting used to the impersonality- long gone are the days of your Family GP... I rarely see a doctor though- usually just the practice nurse for contraception or smear test.
Sometimes, I ask the local pharmacist for advice. They will always tell you if they think you need to see a doctor, or if there's something you can try at home first. This usually relates to my children...
Ive had great success using MyFitnessPal to calorie count and lose 3 stone . I think it should be up for lots of awards for the role it plays in nutritional information, motivation and accountability in helping weight loss- all free, too.
Mental health, the internet is not so helpful. Yes there's information there, but nothing beats SPEAKING TO A HUMAN when help is required.
