RUQ pain spitting blood

Btw I'm 25 and the pain I would describe it as a stabbing pain on the upper right side

Very sorry to hear this is happening to you, you do not seem to be being treated very well at all.  Could you try going private, I  know this will cost, but what price health? You might get seen more quickly for an endoscopy.  Also, you could try taking photographs of the blood you spit up, I know this sounds a bit unusual, but it might be a way of getting them to take more note of what is happening, I had to do this with my tongue recently, just to prove that the pain was not being made up, I got refered to a consultant because of my pics. I also have had to keep badgering the doctor with quite a few visits to get this result, and use the pictures.  Pictures are also evidence!  Keep a diary if your not already of your experience each day, also food diary.  If the Lanzoprazole isn't helping at all, why stay on it the doctor should give you an explanation of why if it isn't helping I came off the Omeprazole they put me on after a week, I knew I'd go back on it if I couldn't cope, but I used herbal things instead and was careful what I ate, it was tricky at times.  Have you tried anything herbal?  Could you have a stomach ulcer?  Spitting out that much blood does not sound good I'd be taking pictures and spit into towels or something and take them into the surgery and show the doctor!  Marigold tea very soothing get it off Amazon.  Don't give in, find one or two private clinics, phone them up see what they could do, have you had a second opinion from another doctor at your surgery? Or go to another surgery and get second opinion if possible.  You sometimes have to fight hard to get what you need these days which is rotten when you feel so ill, hope some of this helps a bit

Can i ask what is a&e? I am assuming its some kind of government clinic? First of all i would go to the emergency room with a bloody towel folded over if that was what it would take for them to know that this is an emergency and i need help now not lansoprazole.. Why are you on this med jf they dont know what is wrong with you. Garlic heals ulcers or any absesses in the stomach so try boiling gsrlic in a kettle of water as strong as you can tolerate and drink this hot and cold when u are thirsty, if there are any ulcers or cuts this would definitely heal them. This should also stop some of the pain or bloating if any . Add a little ginger in the garlic after a week this calms the stomach if you are having spasms and peppermint tea is especially good for the stomach and so is milk thistle.Try to stay off all meds until u know for sure whats happening to you.
