L got swollen lymph nodes in my neck under my jaw, also l being having a sore neck and sore shoulders also a tickling sensation in my neck could these be from a pinched nerve?

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. There may be more than one issue, You may feel the nodes every couple of weeks, if any of the lymph glands doubles in size, becomes painful, ulcerates, or other nodes become enlarged, or you develop fever, or lose weight, you should see a doctor. Wish you good health!
