The following are some of the best ways to get rid of arm pain after drinking: 1. If the pain after drinking belongs to the expansion of capillaries caused by excessive acetaldehyde decomposition products, you can use an ice towel dipped in ice and apply a cold compress for 20 minutes locally to relieve it. 2. If the pain is caused by the accumulation of acetaldehyde and acetic acid in the body after drinking too much, you can take some non-steroidal anti-inflammatory drugs to relieve it, such as aminosalicylic acid. If the pain is caused by ataxia and the arm is hit by trauma, the tendons, ligaments and bones can be damaged by applying topical cream directly on the affected area.
