I have what seems like a swollen lymph node in the left side of my neck for 10 months now, nearly 11.  No illnesses or infections that I know about.  I do have Hypermobility Spectrum Disorder and a diagnosis of Fibromyalgia but this woudln't present anything on blood tests.  Blood tests done in November were normal, and my GP just said it would likely go away on its own.  But now its May and its still there and gotten bigger.  Its now about the size of a cherry.  They did another lot of bloods which have come back with elevated Serum C Reactive Protein (10mg) and elevated Erithrocyte Sedimentation Rate (20mm/hr).  My GP has ordered an urgent ultrasound on a 2 week referral but the hospital have messed up the appointment and I'm still waiting for a date at the moment.  Getting myself worried that this could be something serious like lymphoma.  Anyone else have symptoms / results like this?
