we celebrated work Xmas do Saturday and I drank quite heavily, including port (not normally a red/port drinker). I was fine Sunday morning just hungover but had a nap in the afternoon and woke with stiff painful fingers and wrists. Yesterday morning I woke and my knees and feet joints hurt too. Going up and down the stairs is hard work. It improves throughout the day slightly. I don’t feel unwell in my self. Could this be a reaction to alcohol? Worried it’s something more sinister but it came on so sudden. Any ideas?
