Hi, Sudden swelling along inner arm is generally caused due to extra pressure on maxilla- like sleeping with the arm on the back of a chair or thoracic outlet syn Chat Doctor.  Sometimes it is associated with tingling and numbness in the affected area. Wait for a few days and if it does not improve, then please go for orthopedic consultation. Hope I have answered your query. Let me know if I can assist you further.
