Concerned about the side effects of anastrozole

A number of people have mentioned biotin, also known as vitamin B7, to help promote hair growth. Recently, I came across these articles:
- Biotin, marketed for hair and nails, could skew some medical test results, researchers warn https://www.cbc.ca/news/health/biotin-can-interfere-with-lab-tests-study-says-1.5051992
- The FDA Warns that Biotin May Interfere with Lab Tests: FDA Safety Communication https://www.fda.gov/medicaldevices/safety/alertsandnotices/ucm586505.htm

Here are some key points from the first article:
"It is known that biotin supplements can interfere with lab tests, resulting in false positive and false negative results on a wide range of clinically important tests."
"Health agencies, including the U.S. National Institutes of Health (https://ods.od.nih.gov/factsheets/Biotin-Consumer/), say there isn't enough evidence to support the claims that biotin improves hair, nails and skin, and that more research is required before it should be recommended for that purpose."

@elizm, did your doctor tell you about biotin possibly interfering with lab tests?

I took that drug, it made my knees and joints hurt so bad that I could not walk, I had to change drugs, I am now on Letrolzole, it has side effects too but so far nothing like the anastrozole. I lost my hair, it's not coming back very well, my last treatment was in April 2015.

I have been on arimidex for 2 years. My hair has thinned some. Mostly my feet and heels hurt. Wondering has anyone tried Good Feet ?

After much trepidation upon reading all about the side effects of anastrozole, I listened to those that suggested taking this in the evening. First night I woke up at 2 a.m. with drenching sweats and horrific headache. The headache continued through the next day and I was exhausted. Took it the next night before going to sleep and next day I was tired, but didn't get a headache until that evening but it was a small one. The following 3 days have not been bad at all. I do get tired in the afternoon but find I am listening to my body and sit down in the afternoon. I find I am able to get a lot done in the mornings, relax in the afternoon, and then have more energy in the evenings. My hands do tend to hurt and are stiff, but shall take one day at a time and hoping things go okay.
