If conditions permit, you can also try the medicine: ① Pour 50ml of 5% magnesium sulfate solution into an enamel container and use10ml of hot water. You can soak a piece of gauze in the liquid medicine and wring it out slightly (without dripping water) and apply it to the induration. A hot water bottle is added to keep warm, and it is changed every 5 minutes for 20 to 30 minutes, twice a day, which is better than simple wet hot compress. ② 1 part turpentine and 8 parts hot water (about 50℃) are mixed evenly and then soaked in the induration with gauze. The method is the same as ①, which generally takes effect in 2 ~ 3 days when the skin is red. (3) Hot compress of Chinese herbal medicines, such as Folium Artemisiae Argyi and Flos Carthami soup, is the same as above, or with Ruyi gold for heat dissipation, which can achieve ideal results.
It is said that there is another potato therapy: 40 ml of potato juice, 20 g of dandelion and 0/5 g of urea/kloc-are used to make a "compound potato liniment" for external use. Fresh potato chips can also be soaked in 654-2 injection and applied externally to the induration. Or directly cut 1 fresh potatoes, cut 0.5- 1 cm thick slices, slightly larger than the skin of the induration lump, cover the lump, and then fix it with adhesive tape; After 24 hours, the lump can be obviously reduced, and the patch 1 tablet is applied the next day.
