I literally feel your pain.
I am on Bisoprolol but only 1.25mg/day plus 4mg of an ARB. I seem to have a severe bout of gout after stressing my toes while paddle boarding and climbing down some rocks to get to the water.
It seems BB reduce the kidney's ability to remove Uric Acid.
Plus anti coagulants (I am on Xeralto) can affect kidney function.
PLUS we aren't supposed to take anti inflammatory drugs.
Finally went to the doctor after three weeks and have some Colchicine.
Fingers crossed it stops it along with low purine foods.
Will get a blood test next visit
