Hi all new to this website hopefully someone can help! I have been suffering from heart palpitations, integration, extreme exhaustion, ridges in nails etc for years along with 10 years on going Anemia! Recently had bloods done and ferritin was 8 and b12 100!! Gp gave me tablets and packed me off home. Only until December then came severe nerve pain in Both legs! Prickles all over my body and numbness. It is predominant on left side. Then in the evening my legs burn and feel hit to touch! I'm sure I seriously need the injections! Can anyone give me advice?
