Anybody? Chest pains really.
After how many days?
There is a trend in this sub and usually majority of people who does not treat their bodies well have more symptoms than others, and various pain similar to yours, some has pain in body parts they were hurt as child, or where they had some operation, etc.
As someone already mentioned it gets better with every fast, also treat you body well and with respect in between fasts. It will get better and better.
