Physically i felt a lump on left side of my throat. i have no cough nor felt lump when swallowing. anything to fear ?

Hard to tell: The fact that you may feel something that's new or you never felt before should probably be seen by a physician. There are a lot of possibilities, some good , some bad. However if you notice it changing i would get there as soon a possible.

Nothign to fear: Feeling of a lump in the throat without cough or pain during swallowing is not a big deal; usually it is of no consequence; it is just a perception. If it is anything serious related to respiratory system you will eventually have to cough; if related to the digestive system, you will have pain with swallowing.
