Worried about my hematology consultant appoitment on monday.

I am only 31 with a young child. I have been unwell since October 2018. I first started getting pains near my left hip amd groin. So bad i went to A and E and the gynacology consultant said most probably pelvic immflamatory disease and gave me the antibioltics needed by injection and tablet form for a month. All was well and then in January 2019 I got a bad cough and it was a chest infection got given antibiotics. A week after my antibiotics had finished i had a throat infection again prescribed antibiotics. This recurred 3 times and lasted about 7 weeks had 3 different antibiotics. A week again symtom free and i get another cough , another chest infection and yet more antibiotics. In the mean time i was having left sided flank pain between hip and bottom of the rib cage. They tested me for a UTI as i had blood in the urine but no infection. I got referred for blood tests throughout where they all came back as normal except my white blood cell count being slighly higher than normal but not enough for infection and my crp index markers being slighly inflamed. Chest xray and hip xray clear. Recently i have been getting more worrying symtoms like random fever, sweats linked to fever outbreaks, itchy all over, chest pain, shooting pain near ear in the neck and under my armpit but just left sided fatigue and loss of appitite. I was put on the waiting list to see consultant which was near enough 6 months!!!! When i got this chest pain i was sat on the sofa and it just came on suddenly. I got another blood test in a and e but was told all bloods are nornal and probably anxiety even though  my breathing was not compromised and was breathing nornally was just in pain. 2 days after this i got a phone call an appoitment was on the way in the post for the consultant. I am worried as obviously something is going on but tests are 'normal' so im being told..... but i dont understand if they are nornal why am i being rushed for a hematology appoitment when the wait was 6 months? Im just sick and tired of being unwell constantly and run down, tired and telling my child mummy cant take you to the park today as i feel unwell. I guess i just fear they also wont know or i will be referred for more tests and there will be yet more waiting. I know there are more people out there going through alot more worse things than me so dont want sympathy but guess i just needed somewhere i can write this.
