For ankle sprains, we recommend the use of blood activating and stasis removing plaster, or non steroidal anti-inflammatory and analgesic plaster. But when to use plaster after ankle sprains, generally speaking, it is recommended that patients take plaster treatment 48 hours after injury. For treatment within 48 hours, we recommend RICE treatment. The first step is ice compress. Use ice bags or ice towels to compress the lump to eliminate swelling. The second step is braking, which means that you cannot get down and walk, and it usually lasts for two to three weeks. The third step is to raise the affected limb to eliminate the swelling and pain of the mass. The fourth step is pressure bandage, which is to use bandages or elastic bandages to properly bandage the tumor to promote detumescence. Your question is what kind of plaster to use for sprain. We recommend blood activating and stasis removing plaster and non steroidal anti-inflammatory and analgesic plaster, but they must be used 48 hours after sprain.
