Should I be concerned ?

Hello everyone.

I've come here for some reassurance and advice.

10th December 2023, I suffered with a migraine (I've suffered with them since the age of 16) I'm not 31 and didn't think much of it.

I then became unwell with constant head aches, left temple had a dull ache, very tired and felt sick.

This continued up until January 3rd 2024. Where I became really unwell with night sweats, waking up and ready to go back to bed, still suffering with head aches, unable to eat or drink for 4 days, resulting in being dehydration. I then began to feel better but continued to suffer with head aches/night sweats and looking like have had a shower completing simple tasks.

It's now 2nd Feb 2024, I still have a head ache, still a dull ache in my left temple, very tired, still having night sweats (waking up thinking ive wet the bed type of sweats), weight loss with having a pale face affect and now unwell with cold symptoms.

I've booked a GP appointment but the earliest I can be seen is 17th Feb.

I've read about the increase of cancer cases and many going missed after visiting a gp.

Any advice, please ?

Thanks 

Billy
