Earlier Today I Felt Like I Had A Heavy Feeling

Earlier today I felt like I had a heavy feeling coming and going in my throat (I dont know how else to explain it). I drank 2 bottles of water, felt better so I continued to work. It seemed to go away. For the last hour I have had this same feeling in my throat, along with a headache. I think the headache is because I am tired. I am not sure if I should go in or not.
