Hello and hope you are doing well.
It could be angina, pain due to inadequate supply of oxygen to the heart muscle. This could be more relevant if you are a smoker, are overweight, have a positive family history, are a diabetic and have hypertension. The other causes to consider would be cervical spondylosis (neck problem) or disorders of the nerves, muscle or shoulder joint. It would be wise to consult a doctor just to be sure it’s nothing more serious
Hope this helped and do keep us posted.
where were the pains located as gall bladder attack is nasty and pains radiate on the right under the ribs and into the back ?
