I have PAF and have episodes about 4 times a year at the moment, the last one being in Sept, it's usually sorted with 300mg of flecinide. I,m also om 2.5mg bisoprolol to help me sleep ( I was getting tachycardia/af when lying down. I had a frozen right shoulder a few years ago one had hydrodilation which involves injecting a dye into the shoulder joint then saline, anethesetic and steroids into the joint to over inflate it and break up the adhesions, not nice but it worked. I think recall having af after the procedure, I've just had it done again on the other side and woke up with Af at about 4am, took the flecinide and it settled, but woke up about 8 with it banging about again, it's slipping in an out of af again now although not very fast (70 -80) although it might just be ectopics. Is an orthopaedic treatment like this a known trigger, I must have a bucket of steriods and die in my system!
