Hi Thank you for asking HCM. I have gone through your query. For increasing height you can do exercises like ringing , jogging swimming etc. But avoid weight exercises. Take enough protein rich foods. You can take milk , eggs, fish,chicken which has good quality protein. You can take supplements like whey protein also. Taking nuts like almonds cashews groundnut etc is good also. Citrus fruits will be helpful in getting enough vitamin C also. Also you should have a stress free life and get enough sleep of around 8 hours daily. This will help you increase in height. Regarding the ball like mass on your abdominal area; it can be a lipoma which is a benign mass and harmless. But better to have it examined by a general surgeon. If it bothers you then you can go for excision of it and send for histopathology examination. Hope this may help you. Let me know if anything not clear. Thanks.
