I was diagonsed with PA/AMAG 3 months ago and started to si methyilcobalamin every other day for the past 2 months. I was also taking pregabalin 150mg a day for the burning sensation I have, specially on my feet. For the past 40 days, I was feeling weaker everyday, with an extreme fatigue, became very emotive and noticed that the bleeding at the puncture site when a blood sample was collected took longer to stop (platelets were normal). I was feeling very depressive too...
My wife (always her!) who is also a doctor, wondered if all of this could be a side effect of pregabalin. Well, I stopped to take it 10 days ago and in 24 hours I felt myself more active, fatigue became bearable and the burning sensation did not worsen. It has been like that since then.
I know it's only anedoctal, but I would like to warn you all who take pregabalin that its side effects are very similar to b12 defficiency symptoms!
