So For A While Now When I Eat It's Almost

So for a while now when I eat it's almost like I can feel the food going down my esophagus, it's painful, hard to swallow, etc.. My stomach bloats .. Even if I drink a glass of water . Today my right side of my abd for short periods of time feel kind of like it has gone to sleep and is slowly waking up ... Bowel patterns had been fairly normal .. Burp like crazy .. I often get up in the night to take a tums ... My arms and hands will be totally numb at that time .. Hx of cervical cancer(no radiation or chemo ) total hysterectomy in 2009 also recently I've had horrible headaches (Hx of migraines w seizures). DC'd meds a year ago
What could be w my stomach
