I feel slight discomfort on my right ribs when i move. can this be pulled muscle? i did the laundry 3 days ago and i think maybe thats the reason

Could be..: Yes, it certainly could be pulled muscles. It's possible you strained the muscles inbetween your ribs, called the intercostal muscles, and this can cause discomfort when moving a certain way or even with deep breaths. Try Ibuprofen or Naproxen to help with the pain and inflammation. If it gets very severe, you may also need a prescription muscle relaxant. You could also try a heating pad.
