scared about having brain cancer

so about 3 months ago i was worried that i had a brain tumour, but all my symptoms went away and i stopped worrying.

but since about wednesday last week i have been getting aches in the back of my eyes that have been coming and going. they come randomly and go randomly but they are still happening. i am also feeling kind of sick too but i feel that may be because of worry. the sick feeling comes and goes as well. i have also been having random twitches and stuff on my arm and legs which have only started happening since i found out that can be a symptom (basically could be caused my my health anxiety).

i have really bad health anxiety and am constantly concerned that i'm seriously ill. i feel like my symptoms might be caused by my health anxiety because i recently know someone who passed away with brain cancer so i feel like my worry is being caused by that event. 

what do you guys think? could this all be in my head or do i have proper symptoms? also do i have the symptoms of a brain tumour or am i just worrying about it too much?
