Strange ongoing symptoms

Hi everyone,

I just wanted to come on here and see if anyone else has had any of these symptoms and feelings.

it started last year in the September I started with itching all over my legs feet and arms, I suffer with eczema anyway so I thought it was this but I was constantly itchy with dry flaky skin. I then started getting breathless, right chest and a persistent cough in the morning and night (which I'm still getting now). Keep having dizzy spells and where my heart feels like it's doing a triple beat. I've now developed wheezing that comes and goes and lasts for 15 mins when it happens. I'm a lot more tired than normal and I've noticed my legs aching, my arms, neck and back too. I've been to the doctor just last week and I have been sent for blood tests which I had done yesterday just awaiting results and I'm waiting for a chest X-ray appointment to come through. I've now felt a small pea sized lump in the left of my neck which has freaked me out slightly. Any advice would be much appreciated and I hope you are all ok ️
