Hey,Jack. I heard from other people that you are having sick right now. I hope you can take yourself well. Here are my advices. First,You'd better to go to hospital when you feel uncomfortable. Then,you may need to have rest,do not make yourself too tired. Third, you may need to drink some water or hot honey water. When you feel better, i think you may need to do some exercises to keep your body stronger and stronger. Take care of yourself!
