Hi. I am 19, 5’ 2”, 108 lbs. I’ve had a stomach ulcer for four months before, I’ve started having migraines sometime in December of last year, and I was also diagnose with something called an adjustment disorder , I’m very sleep deprived, I have trouble concentrating, and I’ve also dealt with depression for several years. Lately the top of my head has been feeling weak I guess. It feels like there’s something on top of my scalp that’s applying slight pressure to it. I guess you can compare it to the feeling you get when you have headphones over your head for a long period of time. I’ve been light headed a lot lately, which isn’t new. Is this something I should be worried about? Also,I woke up with a huge migraine and had a sudden urge to vomit , but as always, I just ended up gagging. Could my constant gagging be due to my stomach ulcer that I had? I felt that maybe it messed up my esophagus lining? I don’t know. I sometimes wake up with sore, achy muscles even if I haven’t done anything to make them feel sore. Is there something wrong with me?
