What Causes Blurred Vision, Digestive Issues And Dizziness When Diagnosed With Migraine?

Question : Hello Doctor,
I am having sever migraine, feeling fatigued from a week.
I am feeling dizzy, light headedness, loss of appetite, I eat because I feel weak otherwise I just don't feel like eating at all. I am feeling a sinking feeling in my stomach. I feel constipated but also feel as if I need to use the restroom at the same time. My urine is dark yellow in color. I sometimes have blood in my stool. Also, from last few months there are brown spots on my torso and chest and they keep increasing in number and some in size as well. I am losing weight constantly from last year or so, my skin is turning pale and dark in color, I have blurry vision, it is worse sometimes. I do use glasses. I am feeling bloating in my stomach from past few weeks. My nails are a little brittle and scaly. The soles of my feet have turned really yellow during past few months.

The spots on my skin are dry and they do not itch

I am having migraines since I was a kid. That was not something that had me worried but the symptoms after that are my concerns. Sudden weight loss, constant headaches loss of appetite and everything else.
As you mentioned nothing about those I would like to get your opinion.

Thank you .

No there is no prescribed medicine for Migraine. I just take over the counter painkillers. The picture of the spots has been attached.

Thank you
