Hi, I understand your concern and would explain that your symptoms could be related to a damaged or pinched nerve in the arm or neck. For this reason, I recommend consulting with a neurologist for a careful physical exam and performing a cervical spine MRI study and nerve conduction studies.  Hope I have answered your query. Let me know if I can assist you further.
