I am facing pimples problem since I was 12. I have tried different types of medicines like homeopathic, ayurvedic, allopathic over these years but still at age 27 I am having the same problem. Just the size and type has changed over these years.. This has made my face skin very rough with dark spots... Prob 2 I am also facing weak memory problem. I don't remember sentences or things or words easily.. this problem is becoming worse these days.. Till the age of 20 I had a great memory... Prob 3 I have a feeling that I my muscles and bones are getting weaker... Also I suffer from stiff neck very frequently.. Prob 4: Whenever I get injury then even a minor cut takes up more than 15 days to heal.. just to let you know I don't have sugar.. Also my body parts quickly gets numb/falls asleep whenever I sit or lay in some positions. recently I have undergone master health checkup. Everything apart from Vit B12 was normal.. it was 105...
