Could this be Lyme Disease?

So, I found a deer tick attached to me about a week ago. It wasn't too deep into me so I grabbed a tissue and pulled it off. I went to cdc.gov and looked at the symptoms of the disease and just kept an eye on the spot. The next few days the area was itchy, and the spot where the tick was, was raised and red. Now, (May 28), the spot is still red and raised, but not itchy. Could this be lyme disease? or is there nothing to worry about?
