Sharp pain on centre of chest midnight.

Dear Doctors, I'm a mother of 4 years old girl baby. 6 years back, I had gastritis and got cured with medicines. So, on and off I get chest tightness, acid reflux, blenching if I eat gassy food. Two months back, I took ECG and Echo as a part of regular medical check up and everything was normal. Recently, I have been facing sudden sharp pain at the centre of the chest while sleeping in the midnight. Tat pain is noticeable even in deep sleep. Once I wake up and give movements to the body, the pain goes off in 5 minutes. I asked my husband to pat my back and then the pain goes off. It feels like a sharp gas pain (like a pain while drinking water after eating beetle leaves). I'm a teetotaller. Had sweet beeda a very few times during wedding. So, I'm explaining the pain in tat way. Otherwise, I don't have any bad habits. This episode of pain happened 4 times in last 3 weeks. Otherwise, I'm fine. Is it related to cardiac or gastric pain. Please advise me if I need to meet any cardiologist.
