I've had PA gor three years now after going to the doctors with extreme tiredness and numb toes n pins n needles in arms n fingers. I get injections every 12 weeks and they only seem to last me 5 to 6 weeks. I've been numerous times crying asking for it earlier but they so no n that I must be depressed. I get depressed after about 5 weeks coz I'm that tired I have no life !! Aches in pains in my joints , blurred vision , horrible palpitations n fatigue, memory loss, freezing cold pins n needles. Dizzy n faint . My eye sight is worrying me quiet a lot. I'm looking for advice of what to do or buy to make things better for me. I've tried b12 tablets n they don't gelp. I wish my doctor could give me this every 6 weeks n my problem would be a lot better. I feel like a hypochondriac it's awful. I also haven't been told what my levels are like I've read some gave been. They just say there low but ok for a 12 week injection
