Chest pain when lifting heavy objects is commonly caused by problems with the soft tissues of the chest, such as chondromalacia or thoracic costochondritis, as well as contusions and strains to the soft tissues of the chest. The thorax must be strained when lifting heavy objects, which can lead to localized pain. If it is a localized chondritis or thoracic rib chondritis, it can be treated with oral NSAIDs to eliminate the local inflammation and also to relieve the painful symptoms. If it is a local inflammation or other chest injury, you can also give topical ointment to reduce swelling and pain and activate blood circulation at the painful location. You can also do local physical therapy, such as infrared therapy, microwave therapy, medium-frequency pulse electric therapy, etc., which can promote local blood circulation, accelerate local inflammation or pain dissipation, and also have a role in promoting the recovery of injured tissues.
