Tin allergy

Easy enough to figure out if it is yeast. Switch to drinking bottled Cooper's beers. Swirl the sediment in. If you continue feeling fine, it's unlikely to be yeast.

Ask your GP to refer you to an immunologist. If required, change GPs. You are lucky to have stumbled onto the fact that your wellbeing is affected by something environmental and are now in a position to look for the cause. It can be a long process, but it is worth it. I lived with an undiagnosed allergy to nitrates for years and years. Now that I know about it, I can manage it. It's not easy. In my case a slice of bacon or ham can leave me with hives and reflux that lasts for 3+ months.

BTW: An immunologist can give you a series of standard tests for common allergies. Those tests give you results pretty quickly. The more unusual allergies will require a more time consuming approach, such as an elimination diet.

Gluten intolerance?

Thanks @peteru - how many beers - do you think just a few would show up if was yeast?

No gluten intolerance - I eat bread, pasta...

If you think it is an allergic reaction ask your doctor for IgE levels and Tryptase on a pathology request form but DON'T get your blood taken till just after you have your next significant reaction. As for doctors with diagnosing allergic reactions , most have a very limited knowledge. You have to see a specialist.

swap to pints

maybe your back is sore from pouring to many schooners?
Getting in and out of the lounge chair
bending and turning on tap / opening door etc ?

pints are worth a try

lifting kegs into the keeeezer make my back sore sometimes

Buy a case or two and drink it at the same rate you would drink homebrew. If you drink 2L of homebrew a day over a week, then drink 2L of Coopers a day for a week. If you see symptoms earlier, you can stop then and see how long it takes to return back to a symptom free state.

That will also give you an idea of how long it takes to recover from your reaction to whatever is that triggers your symptoms. In my case, the onset of symptoms was in less than an hour, but it took several months to clear up. It sounds like you might be in a much better situation and can recover within days or weeks.

@peteru Thanks

Well my plan is to do exactly what I have been doing next week... or I mean what I was for the last 4 years , and see if it comes back..
Are you saying felt something after an hour? WOW and what symptons?

I have been some research... 2 different homebrew suppliers, both white lining, tinned fish has a greyish colour... maybe not being 'food' and less scrunity they have let it go...

Lots of articles on BPA - 'moving towards BPA free' - 2016 67% of cans were still had or have BPA and as I said not being food - less scrutinity but ironically drinking will absorb 2.5 x easier...
