Lymer do you have a fever? That is a very major symptom with meningitis I know with Lyme a fever can be 99 depending on how your body temp normally runs. I would be listen to my body but severe neck and shoulder pain is very common with Lyme. If you get a fever along with the stiff neck or multiple symptoms dizziness, loss of vision etc then go to the ER! Good luck and I hope it is just another symptom. Sending positive thoughts!!
