I am a 37 year old male. I have been experiencing tightness below (not under) my right rib cage accompanied by very bad and frequent gas. Sometimes it feels like a grabbing sensation , not painful just uncomfortable. Also get a tightness in my back that seems to be associated. I suffer from tinnitus and it seems to get worse when I get this sensation. Also, when I wake up in the morning my mouth is extremely dry and I seem to be thirsty quite often. Lastly my hands often feel stiff and swollen especially in the morning and I sometimes feel light headed and sensitive to light.
Any ideas what this could be?
Thanks for your help.
