Why Do I Get Worsening Headaches, Blurry Vision, Nausea, And Muscle Spasms In The Mornings, Especially After Stretching, Or Eating?

Hello? uhm I m Andrew a trans teenager ig. For about a year now I ve been waking up to headaches, I found out that when blood reaches my head the headache gets worse, medicine or eating doesn t help and makes it worse. Sleeping for me isn t easy and I struggle with it a lot. Before the headaches, I stretched my legs in bed just because, and now when I do it in the mornings I get muscle spasms and I shake constantly. When my headaches pulse sometimes I get blurry vision and now I ve been feeling like throwing up after eating something, so I don t eat until I go to bed. Where I live I don t have a paramedic here nor a dentist and my family and I are very poor so I try not to make a big deal about my health.
