Pain in head following a cold

I recently had a cold a few days ago, and am now almost back to normal, but I now have something strange going on. When I swallow, sneeze or press slightly on the lower back of my head on the right i get a dull ache. it only lasts as long as i swallow or press on it and after i gulp or remove my finger its gone and it doesn't hurt otherwise.  Could this be related to the cold I just had? My nose is still a little stuffy but I can breathe thru it now.
Thx.
