Stress & anxiety & depression definitely without a doubt increase pain levels in fibromyalgia sufferer's.Not one known painkiller or SSRI treatment works on me.Saw my private sector pain consultant surgeon aweek ago & I asked him what happens if you were in a accident etc of any kind & pain killers won't help in anyway,he told me the only relief you would get,is it you knocked out with sedation 🥺.I'm on butec transdermal patches being 30 mcg for 7 days then you replace them.
To be honest they only take away about 6 to 10 % of the pain of 100.
They supposed to be 60 to 100 more potent then morphine.
As other painkillers don't work or SSRIs I have nothing for breakthrough pain,so live in somewhat 24/7 agony.
