Diagnosed with CLL in 2024 I am now worried as I can feel more lymph nodes in my neck

I was diagnosed with CLL in  2024. But I also have fibromyalgia and osteoarthritis and psoriatic arthritis and back issues.  I’ve recently been unwell with a bad cough/cold had 3 lots of antibiotics to clear it then for the last 3 weeks I’ve been suffering with a really bad back    I’ve lost 3 stone being on Wegovy.   But I’m now worried as I can feel more lymph nodes in my neck   I’ve ask to see my consultant every 6 months instead of 12 months. No appointments have come through.  I’m also starting to suffer with my mental health again with all that’s been going on in recent weeks.   I’ve had a  lot of mouth ulcers on roof of my mouth they have not gone but I’ve got them under my tongue now. What should i do.  Contact my GP or see my CLL nurse.  I just don’t know what to do for the best
