This is a Clinical crossover trial study. In this study, 100 patients with type II diabetes will be selected based on entry and exit criteria, then randomly divided into two equal groups (group A and group B).In the first three days of the first week of hospitalization, in group A insulin injection with a 90-degree angle and using Nidel 32-Gauge with a length of 5 mm, and in the other group insulin injection with a 90-degree angle and using Nidel 32-Gauge with a length of 8 mm will be done. After a one-day break, in another three days, the types of needles used in the two groups are moved together. After a one-day break, in another three days, the types of needles used in the two groups are replaced together. Then the VAS scale will be used to assess post-injection pain; the amount of leakage after the injection will be measured in two ways Yes/No, according to the researcher's observation. And to check the effect of Needles on controlling patients' blood sugar, their blood sugar levels will be measured based on the routine of hospital units.~After entering the data in SPSS20 software, the collected data will be analyzed using descriptive statistics (frequency, percentage, mean, standard deviation) and statistical tests (t-test, chi-square).
