Sorry to hear about your troubles. Chad is the expert here, so I would defer to him, but here's my 2 cents.
As much as I like alt. med., seeing a western MD might be a good idea, particularly for your digestive trouble. Western medicine can often be used together with alt. med., but let each practitioner that you see know about what you are getting from the others. In addition to seeing an acupuncturist, you may want to see a Chinese herbalist, or ideally someone who does both.
Check in with your practitioners about dietary changes. Given the hot digestive problems that you mentioned, I would suggest avoiding spicy, fried, fatty, processed, and chemicalized foods. Coffee, smoking, drinking, and drugs are also good to avoid. Chinese medicine generally recomends against ice cold foods or too much raw. Diet is a major element of Chinese medicine, and is praised by some classical texts as being more important than herbs.
Meditation may be good for you, but maybe not in the short term if it is agravating your symptoms. Your meditation teacher may be able to suggest modifications in your practice that might help, such as lying down instead of sitting. You could also be trying to breath too deeply. If you are practicing on your own, I would recommend having a teacher check out your form first.
There is a last piece of advice that I would give, at risk of seeming too explicit. Generally, for men with chronic illness in particular, Chinese medicine recommends not ejaculating frequently. According to the classical texts, ejaculation during the winter time is 100 times worse than in any other season.
I hope that this advice helps. You should probably take the advice of your practitioners before anything I say though.
