Hello, Thanks for your query. As a primary treatment, you can start taking mild pain killers like acetaminophen or ibuprofen along with hot fomentation and adequate rest to the arm muscles. You can avoid doing exercise for a few days and take vitamin B complex supplements for nerve related symptoms. In case the symptoms do not show any improvement over next three days or are aggravated then you need to consult an Orthopedician for a clinical examination and specific treatment I do hope that you have found something helpful and I will be glad to answer any further query. Take care
