If you have an Urgent Care facility I would go see them. If not you will just have to wait on appointment or go to ER
I am NOT a doctor, but I did experience similar systems when I contracted Mono. I noticed the swollen lymphs nodes after my boyfriend kissed me goodnight on the cheek, and it was strangely painful.When I went to the bathroom and looked closer I counted 13 swollen lymph nodes they were behind both ears, on the side of my face, throat and neck area, and under my arms.The next morning at the doctors office I counted 20, and eventually they moved down to my groin.I had some abdominal pain, and a complete loss of appetite. If your pain persists or worsens I would absolutely seek professional care ( For example mostUrgent Care facilities will accept most insurance, and no appointment is needed, that is where I went) especially because of your already present conditions. If not I would wait until your appointment.Hope this helps.
