What you have probably done is to disturb some mineral build up in the pipes and now it's blocking the inlet ports of the kitchen faucet.
Is this a one handle or two knob faucet? First remove the aerator vandtry the water without it on the spout. Can you get water now? If so then clean the aerator screen. Still no water? If one handled turn the
Water off and open up the valve. Remove the cartridge and check and clean the inlet ports. Now ,with the valve still open , turn the water back on to flush out the supplies. Work better now? Tom

It is a two knob faucet and I have already took the aerator off and still no water

Clean Aerator first. Clean it under running water. Run water through the spout for few seconds. See if you are getting good volume. Reinstall aerataor.
