Body aches and pains on the second day of heavy work can be relieved by medication and rest. 1. Medication: For those who have body aches and pains due to heavy work, non-steroidal anti-inflammatory and analgesic drugs can be taken to improve the symptoms, such as acetaminophen tablets, celecoxib and other medications, which have the effect of relieving generalized body aches and pains. 2. Rest: Body aches and pains caused by heavy work are mainly due to the accumulation of lactic acid in the body, so you need to get enough rest. Generally, after sufficient rest, the symptoms will gradually be relieved, and the generalized pain will also be improved. Soreness caused by heavy work usually does not require special treatment. If medication is used, it needs to be used under the guidance of a doctor and should not be used on its own to avoid adverse consequences. If there are other serious symptoms, you should seek medical advice promptly to avoid delaying your condition.
