Past 6 years i have severe problems sitting down with numbness, have problems with chewing and swollow my food i throw up if i ate too much?

2 problems: I wonder if you are experiencing sciatica due to circulation problems, or if you Are overeating and this is possibly due to obesity? The second problem is gastroesophageal reflux, and can be relieved in several ways - small portions, less fatty and acidic foods in diet, antiacid therapy - Tums/Rolaids and proton pump inhibitor medication such as Omeprazole. See a dietician and your GP for a plan
