I have also experienced a lot of the same things you are going through to including facial swelling & digestive issues. The ONLY things that help me are oil of oregano, grapefruit seed oil & a very good probiotic at bedtime (never take during meals). I have to watch everything I eat also but since I have been on these 3 products my lifestyle has improved dramatically. All the doctors I have been shuffled around to have been baffled by my facial swelling, etc. I am telling you this as I did not get better at all until I started the above products mentioned. Your stomach issues are most likely caused by candidia infection (fungal). I have been healing my stomach & sinuses as I believe both these areas were infected. I have dealt with this off and on for 34 years now & this is the only time ANYTHING has worked for me. I also drink a protein shake every morning to help with digestion. All my issues started after an infection that ran wild through my body at age 34 & the doctors did surgery, then gave me the largest amount of antibiotics in the history of this hospital. These antibiotics saved my life but wrecked havoc within me ever since. I did not realize all this until last year. I now stay away from antibiotics unless it's a life threat that I need them. Please go see a good Naturopathic Dr. or a certified nutritionist as this is the only true help I have received. Oh, my facial glands were also so beyond swollen that my neurologist thought I Sjogren’s disease & my blood work showed very high levels for RA. My C Reactive protein levels were off the chart also. I see a specialist at Jewish National Hosp. in Denver next week but feel I really don't need to see him now (had to wait 2 months to get in). Anyway I really hope you take what I have said to heart as it may well be the same kind of issue I have been dealing with. I am so thankful for the naturopathic approach or I would still be super ill right now.
