Convinced I have a serious fatal illness

I've convinced myself I have a serious fatal illness and I'm not sure what to do. Deep down I know that maybe I'm over reacting but the fear is real. Last week I started with pain in my upper back and my right side. This persisted for a few days, then I started to get a sharp pain in my right side but lower down towards my back but only when swallowing say a drink, not food. The pain in drinking is still there like a sharp pain. I just another post somewhere about someone who had an aortic dissection and now I'm consumed with the thoughts that this is happening to me and I've worked myself into a panic and I'm convinced I'm going to I die suddenly from this. Has anyone else had anything like this?
Just to add I do have diagnosed gallstones but this IS NOT that. I just know it's not because it's a different kind of pain and I've had them for three years. I do have diagnosed OCD and anxiety but I've been well for a long time now. I just can't shake this feeling something is seriously wrong.

I know we are all tempted to self diagnose as we google every symptom-my GP recently told me that it can throw them off a diagnosis (she didn’t say it but I’m sure it drives them mad). I don’t have health anxiety but went convinced I had thrush for months on end and also anal fissures, self treated and when they didn’t clear up it transpired that my symptoms were all related to menopause and I needed hormonal treatment. I’d been calling the surgery for repeat meds of the issues I presumed I had, thinking I knew as I’d had them in the past. I’m fine now I have the correct diagnosis. Taught me a lesson.

If you have gallstones it could be your pancreas causing this. I have chronic pancreatitis (caused by gallstone damage) and get pain in upper back and right side. It’s most likely linked to gallstones. Hopefully you’re on a wait list for removal. Get them out, they can cause a lot of damage as i’ve found out (thankfully for most they don’t cause life long problems).

If the pain is new, persistent, or worsening, the safest thing is to contact your GP or an urgent care line so you can get checked properly rather than trying to self-diagnose. Even if it turns out to be something minor, you’ll have peace of mind. In the meantime, try to step away from googling symptoms—it often makes anxiety worse.

If you have gallstones I'd be concerned they're causing pancreatitis now with your symptoms, GP today and ask for bloods to check your pancreas (serum amylase levels).

How ate you today OP? Did you get to speak to a GP?
