Twice in recent days I have seen reference to numb fingers on this forum. Additionally Rellim and I have swapped observations about numb feet.
I have an intermittent problem with numbness in my left hand which may be due to carpel tunnel syndrome but it's worse since my ablation. A suggestion was made to me that the numbness in my extremities might be due to poor circulation as my heart is not so efficient at present.
I have Flecainide packages from several manufacturers and have just read through their instruction leaflets. One states : possible side effects - occurs in less than 1 in 100 users - damage to nerves in fingers and toes causing numbness.
Perhaps that's the answer!
