Black stools generally mean old blood and can have a jelly like consistency. Black vomit suggest your bleeding in your stomach or close by. It's important to have this investigated very soon. If happens again today please visit an emergency room. There are many causes of internal bleeding none which can be sorted without investigation.
A lot of red wine and spinach can give a similar look.
Tamoxifen is very unlikely to be related to any of this.
Thanks I will be having it checked out. Cheryl x
Morning Update for you and thank you for all your concerns.
I
had my gastroscopy and a biopsy has been taken and waiting for the
results.After the procedure the Dr said everything looked fine and he
didn't find anything of concern to him ,I had a whole heap of bloods
taken so waiting for the results as well.
Sorry I was rather slack, but you get to the stage of not another problem. now just have to wait for the results.
Thanks again Cheryl xx
