If the twitching is caused by EBV, then chances are it will go away as you recover from the virus. In the meantime you may want to get tested for other things, but your symptoms (sore throat, swollen lymph nodes, enlarged spleen) are all classic symptoms of mono/EBV. So that's most likely what you're dealing with. The good news is, most people have a fairly quick recover, so hopefully you'll start improving soon!
