You can go to the local infectious disease hospital or tuberculosis prevention and treatment center for examination. If you are diagnosed with tuberculosis, the government will provide basic anti-tuberculosis drugs free of charge. These drugs usually take 6-8 months and may have some side effects, but they must be taken according to the course of treatment in order to be cured as soon as possible. Don't need to be hospitalized now, pay attention to rest, don't be too tired (tired body resistance will be reduced, which is not conducive to the treatment of diseases), and try not to eat irritating foods such as peppers. Don't spit everywhere in daily life. You'd better vomit in a spittoon filled with disinfectant. If there are no conditions, you can spit on the paper and then fold the paper and throw it away. Wear a mask during the infectious period. Your family members should also have a check-up. If you don't have tuberculosis and have not been vaccinated with BCG, you should replant BCG and share meals with you at ordinary times.
