Iam 32 Male. From last 1 year iam experiencing mild pain in my LEFT shoulder / arm /hand. I did not care much as it used come sometimes and disappear later. However from 3 months the pain is severe. I feel burning sensation in my shoulder and hands for 3 to 4 hours in night and morning. Sometimes it disappears for 5 to 6hr. (Sometimes i feel like my shoulder is cut that much pain) Iam getting this pain daily now. Please suggest whom to consult? Is this something serious. (No Accident or injury history is there) I used to lift water can 10liters on my shoulder from near by water shop which i have stopped from 6months.
