My dad is back in the hospital. He spent last night having diarrhoea (the stools were black... Not good!), vomiting, and nearly passing out. They placed a tube in his nose to pump out the stomach content, and what came out was also black. It sounds to me like he’s had some sort of internal bleeding (my guess is perhaps the anticoagulant he’s taking has something to do with it). I’m awaiting more news from my mum. Please send some prayers and healing vibes.
