If no pics, then describe every bit of the plant, stem colour, leaf colour from bottom upwards. where grown outdoors, indoors, in soil or pots, when do you water, ventilation indoors, what tomato plants.

Ok, next, do you know which variety it is?
Some grow bushy with more than one 'branch' some need to be pruned to keep them to one stem...

Have a look at this advice about removing side shoots, which I think will help
