Neck Pain and Chest Pain after Eating.

Recently i underwent Endoscopy and found Antral gastritis with H pylori positive so i was asked to take Esogress HP Forte for 2 weeks followed by Vonoprazon 20 mg for next 4 weeks. Along with this i have constipation and fissure due to which i cant pass my stools sitting i need bend and with the help of finger i need to pass stool. The problem is i am getting pain in the shoulder chest and major is in the neck and the pain is associated with swallowing difficulty as well. This swallowong difficulty is not always but some times it happens. I had been to Physiotherapy Tens and more but pain is not reducing. I have taken ECG, ECHO 2D recently and  CT cardiac 2 years before Cardiologist says it is non cardiac chest pain. I feel very discomfort especially in the evenings. Can you please help me how can i understand what is happening with me.
