Excess salivation, facial nerve pains & food allergies need help plz Dr.! photo attached

Assalam o alikum,
Sir how are u. I am facing excessive salivation sometimes become foamy white, stingy and bubbly specially at night since january'16. I also faced stomach pain, indigestion and not able to eat spicy, hot and hard foods. My head is elevated 1 to 2 foot at bed time.

In this regard i have done h.pylori test which come clear. Further, i am started having intermittent facial nerve pain over face around mouth since march. The nerve pain are sudden, sharp, pulsating and comes and goes and got worsens at night specially after dinner. The salivation increases and big saliva bubbles comes out of mouth at the same side of nerve pain at midnight.
I have Recently done abdominal ultrasound which is also clear. I have went to numerous GP but nothing diagnosed except anxiety, primary diagnoses neuralgia and dyspepsia. Currently by a neurologist, I am put on medication omeprazole, gaviscon, cipralex (anti-depressent), tegretol (anti-convulsant), added hexidyl, added rivotrol. The only medication tegretol and cipralex is working well on me to control pain and but my salivation does not stops.
At the start of all this problem in january i faced chest pain, burping, food allergies up till now as said above which shows that there is something not working properly in stomach. I have been advised to have barium swallow test.
I have decided to try homeopathy medicine soon just not to control my symptoms but curing as well. My life has become miserable. I have attached my salivation photos. Kindly give me advice over this specially what has happened to me or any medication which can solve this problem completely.
May Allah grant you Jannah.
