mild analgesics and change food habits.

Detailed Answer:
Hello and welcome.

Thanks for sharing your concern.

After reading your history it appears that you might have food intolerance.There is nothing to worry much as it does not involve your immune system.

The best way to get rid of this is keep rotating your food products.Do not continue with the same food for more than two days.

you can do the following and see the results.
1.Reduce stress and chemical exposure.
2.Improve your eating habits.
3.Eliminate food that is suspected to cause intolerance. Dietary supplements can be introduced.

Swelling and pain should reduce upon doing so.If required you can take mild pain killer for three days.

This should help.If you find the problem persists then you must see your gastroenterologist for various blood test and kinesiology test(for muscle and joint strength detection).

Please let me know for further query.

Thanks.
Take care.
