The foot-soaking moxa stick you mentioned above is a good way to keep fit. Insist on supplementing some nutrients, cook 800 porridge with red bean soup, cook yam and astragalus root to strengthen the spleen and stomach, or introduce you to an acupuncture point and shoulder well spring with internal customs and appearance by self-massage physiotherapy. Stick to self-massage for half an hour every day and the problem will be solved.
