It is possible that the symptoms you reported might be related to either a vascular or neurological disorder. If the blood supply in the fingers is insufficient, then you might feel numbness, tingling and/or muscle cramps.
You might want to visit a neurologist to check if there is a nerve affected.


There are three big nerves responsible for the entire arm. All of them are reaching the palm. Depending on the exact location of the symptoms the doctor might be able to determine which nerve is affected. However, it might need additional examinations in order to locate more precisely the location of the problem because the affected nerve stretches from the neck to the fingers.
