Hello and thanks for posting,

I can appreciate your questions. I think it is important to wait until the bone scan results. Your GP can actually prescribe vitamin D as well if needed. You can have a blood test done by your GP to measure your current vitamin D levels. So let them advise you on a calcium/vitamin D supplement. Ask them about your pain and see what they suggest. Joint pains can be helped by yoga, pilates, and distraction therapies. Some people look into complementary therapies such as acupuncture, or aromatherapy to help. 

There is information on the NHS website about osteoporosis and vitamin D

Usually Omega 3 and glucosamine are ok to take alongside other medications but let your GP know. Most high street pharmacists can advise about taking supplements with other prescribed medications. We can't really advise you about these. Most supplements are licensed as food supplements, so don't always have in depth data about their effectiveness. Collagen is an example, it is a lot of joint care supplements but doesn't have in depth scientific research to explain or support it's use. Yet people do report an improvement in their symptoms after taking it. The UK organisation versus arthritis have information about collagen.

Penny Brohn Cancer Care have information around diet supplements and other complementary therapies.

You might want to post in the general section of Cancer Chat, where other users can see your post and may reply with some tips.
