Im scared i have cancer. Please help

For the last year ive had loads of uribe infections and genuinely feeling unwell and exhausted. 

 

I went to the drs a month ago for cold feet and mottling on my thighs, they did full blood test checking inflammation and kidneys and evrrything else and it all came back fine, i also had a mri which was fine.

 

My symptoms are:

Diarrhea every morning 

Nausua

Tiredness

Pins and needles sometimes in legs feet hands and face but this is not always. 

Loss of appetite 

Pale skin

I had a rash a few months ago which they put down to allergies but i had not changed anything to cause me to have a allergic reaction

I get pain in my joints especially my toes and hands

I keep getting eyeache and a headache in my eyes.

I have floaters and flashing lights in my vision.

No energy to do anything

Emotional but i dont no if thats due to being worried

I get itchy feet and palms of my hand. 

I had a itchy bump come up on my hand that then turned to a bruise, my joint in my thumb was hurting for a coupke of days.

I also have brown bleeding in between periods and light headness

 

Dr reffered me to rheumatology and they done some specialist tests and dr said my igg levels came back high but she doesnt no what that means so waiting for hospital to call me. 

 

Im so scared i have something wrong. Everyone thinks im a hypercondriact however u spell that. But i feel like something is wrong
