Hello, so I went to the GP with severe pain in my abdamon, swollen abdamon, urinating a lot but no pain or burning, she did I urine test and it came back there was urine which I suspected as I thought it looked like it was there but unsure, she felt my abdamon and couldn't feel anything, did bloods and urine came back as no sign of uti or infection, bloods came back anemic, high white blood count, so she has sent me for a urology mri mid november and also a camera I believe into my bladder the week after, I still have a swollen abdamon, it is more above my belly button and stomach feels hard, but this morning I woke up at 8am with the worst headache I have ever had, seeing white spots and I threw up several times, felt faint and legs like jelly, confused 

Almost 17 hours later my head still hurts but not as bad as it was, my body feels like jelly and I csnt face food. No chance of pregnancy or bug as I'm agoraphobic, and a while since I saw the GP, I haven't had a migraine for over 5 years, I just wondered if these things could be linked, if the migraine and sickness could be apart of anything possibly wrong, I just wanted some advice, I am only mid 30s, and worried about the camera test especially thank you
