A felt clicking is likely to be a bottom bracket or pedal bearing problem. Chain problems tend to be audible clicking or clattering.
If the click is felt on one side only that points to a pedal bearing problem rather than bottom bracket.
A constant stiffness, roughness or 'notchiness' as the cranks turn would indicate a worn out bottom bracket bearing.
You can check the pedals by simply turning them by hand. If they don't turn smoothly the bearings need greasing, servicing or replacing.
You can also check the bottom bracket in a similar way by turning the crank by hand. Taking the chain off the chainrings makes it easier to feel stiffness or roughness in the bearings. Also check for play (slight looseness) of the crank axle in the bottom bracket bearing.
If you are not familiar with bike repair, it’s best to have a local bike repair shop check it out. Bottom bracket replacement is best done by a repair shop in any case as special tools are needed.
