There are three main reasons why you should not drink after a sprain: 1. In the acute phase of the sprain, if you drink alcohol, it will lead to vasodilatation, the blood vessels in the sprained area will rupture and bleed, which will lead to increased bleeding, resulting in swelling and inflammatory edema in the sprained area, which is not conducive to recovery. 2. After a sprain, you usually take oral anti-inflammatory and pain-relieving drugs, such as Nimesulide and ibuprofen, etc. If you drink alcohol, it will lead to further damage to the gastric mucosa. The sprain is usually followed by oral anti-inflammatory and pain relieving drugs such as Nimesulide and Ibuprofen, and drinking alcohol can lead to further damage to the gastric mucosa. 3, drinking after a sprain can lead to subconscious movements, leading to further damage to the sprained area, and unsteady walking after drinking or inadvertent movements during sleep at night can lead to increased damage.
