Brain tumour?

Lately ive been feeling really unwell.

Ive been weak, my legs and arms feel like jelly and i have a lot of tension in my face.

My eye has been giving me a lot of trouble, its been feeling heavy and uncomfortable.

Ive been to hospital and all my blood tests came all good. I have been to an optometrist and they said my eye is fine i just need glasses.

But i still feel terrible and so does my eye.

Could I have a brain tumour???

*sorry for posting in here im just extremely stressed and need urgent answers!*
