Cops are investigating a woman’s claims that she may have been stabbed with a needle while entering a Midtown subway station Wednesday night, sources said.

The woman said a man bumped into her at the N/R station at 49th Street and Seventh Avenue at 7 p.m. and she felt a slight poke.

She went to Mt. Sinai Hospital Queens in Astoria as a precaution.

Cops were looking for a man in his 40s in relation to the possible attack.
