Thanks so much for your responses ladies. I really appreciate it. Just to give you all an update....
I started taking some magnesium San pellegrino each night and this definitely helped things move along (@"Michele B" im not sure if this is the same as magnesium citrate?). I then spoke to my plastic surgeon who referred me to a lovely medical oncologist who I met with a couple of weeks ago. She spent about an hour with me going through everything which was great. Long story short she said obviously it’s not ideal to be on coloxyl and magnesium for too long if I don’t have to be so she said to stop the Tamoxifen for 3 weeks and see how things go and also try and slowly stop the magnesium and coloxyl. I have stopped the magnesium but still take the coloxyl as unfortunately I’m still having issues with bowel movements. So looks like it may not be the tamoxifen at this stage. She said if that is the case I’ll probably need to get a colonoscopy to look into my issues further. I also had my bloods done to check a heap of things and get those results next week when I speak to the oncologist again. To be honest it’s all doing my head in 😣 I know things could be a lot worse so I need to be thankful for that but I just need answers. Hopefully I’ll have them soon. So sorry again for the waffly message but it’s great to have a vent sometimes. Thanks for reading xx
