enlarged lymph nodes in neck

About 6 weeks ago I noticed an enlarged lymph node on right side of my neck.  Since then, I found 2 more on the left side but slightly to the back.  The others I have found are bigger than the original one 

All are hard, don’t move and are not painful, but I seem to be able to feel them slighly less sow hen I push on them.  When I found the first one I thought it might even be a muscle knot, but now I definitely think they are and feel like lymph nodes - no other symptoms 

GP appt tomorrow 

anyone else got/had similar and what do/did your lymph nodes feel like 

thank you
