The pain in the arm of nasopharyngeal carcinoma may be clinically caused by the following reasons: First, patients with nasopharyngeal carcinoma may undergo chemotherapy during treatment, and the side effects of some chemotherapy drugs may cause peripheral nerve reactions, resulting in pain in the arm, which can be accompanied by local numbness and other related reactions, which may be related to the neurotoxicity of chemotherapy drugs. It is generally recommended to drink more water and promote the excretion of drugs, and if necessary, pain relief drugs or nerve-nourishing drugs can be used to relieve the discomfort. Secondly, bone metastasis of nasopharyngeal carcinoma, after bone metastasis, bone pain in the arm can appear. Generally, bone scan is done to roughly determine whether there is a possibility of bone metastasis, and bone metastasis in the arm of nasopharyngeal carcinoma is still rare. All in all, for the pain sensation at the arm of nasopharyngeal carcinoma, the causes and characteristics of pain should be carefully analyzed for symptomatic treatment and treatment.
