<s>[INST] Hello Im 16 years old, and I have been receiving this pinching pain in my chest. It feel as if I have a needle in my chest. Whenever I move in a surtain direction it starts to pinch! Im wondering if its my ribs that are doing it or something such serious?Ps. Do I have to pay for an answer? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. You are having pin and needle sensation. It is common in anemia (low hemoglobin) and vitamin B 12 deficiencies. So better to get done blood reports like complete blood count and vitamin B 12 level. If any of these is deficient than you need supplements. Sometimes stress and anxiety can also cause similar kind of needle pricking sensation. So avoid stress and tension, be relaxed and calm. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks. </s>
