Can grapefruit cause joint pain

Answer 1

Yes, based on my experience and other people's experience. Please see here for a report on knee pain (http://www.articlesbase.com/diseases-and-conditions-articles/grapefruit-juice-causes-knee-pain-1875707.html). Here is my direct experience:

I love grapefruit but I have similar suspicion that grapefruit juice is the cause for my backpain. I had a severe backpain about 2 years ago. It lasted a few months. When I evaluated what I did differently, eating grapefruit was one of the possible reasons. I only began to suspect it because grapefruit is reported to interfere with many different drugs. I stopped eating any grapefruit. Gradually my Back pain went away. I started to excise a lot for my back muscle. I swim 30min-1 hr everyday. I was back pain free for almost one and half years. There was not additional proof for my suspicion until a few days ago.

Last week, my wife bought some large delicious grapefruit from Costco. I couldn't resist. I started to eat one everyday and I ate 2 large grapefruit 3 days ago. On Sunday morning, I suddenly got severe back pain again that I could not put on my socks. When I evaluate the situation in the last 1-2 weeks, the only thing out of ordinary is eating grapefruit again.
