Stomach Pain

I have been having stomach pain for the last 2 weeks ranging from mild / dull pain in the stomach area to serious heartburn and pain in the left shoulder blade.When the stomach is in pain ars album 6 every 2 hrs seems to relieved it but only to be followed by a hearburn and I would use Nux 6 every 2 hrs. When the hearburn gets worse Nux 200 makes it better for a day . The pain comes back 30 mins to and hour after meal the following day.I noticed it gets worse if i did strenous execise the previous day.
I am male 49 yrs 70 kg 170 cm ht. In 2004 I had similar problem which I overcome by diet change and homeopathy ( mainly Nux,Lyco and Ars ) 7 months ago I was 75 kg and I wanted to loose some weight to improve my BMI. I have been on a low carb starch diet, no sugar,very much less processed food , lots of vege fruits,oats, peanuts, fish and daily raw eggs, raw honey,raw goat's milk, cold pressed coconut oil for cooking,wild chicken , occasional buffalo meat, omega 3.My local homeopath also introduced gymnema selvester herb as a preventive measures for pancreas health which I take one capsule 3X daily. I feel a lot fitter higher energy level which led me doing more exercises including the strenous ones occasionally. No complaint about energy level.I sleep at 10pm and wakes faily early 5 am feeling hungry usually. sometimes 4 am. I also notice I feel a lot hungrier quicker in the last 2 weeks. I manage this by having heavier snacks in between. Regular stools once or twice per day .My blood test indicates everything normal except my Total cholesterol 233mg/dl and LDL 157 mg/dl.
Trygleceride 79mg/dl,Hdl 60mg/dl and ratio chol/HDL 3.9. Depending on what I eat and level of exercise my fasting glucose 88-108 mg/dl and random 90-115 mg/dl. I am not on any allopathy medicine .Please advise if I am doing something not right and should try different homeopathy medicine or make changes to what I eat or do ?
Thank You.
