yeah you're right about the constipation and I was constipated at the time so it could be due to impacted colon.
Could you, if you know, describe the mechanisms of how this causes instant bloating?
I don't usually have nausea except like once a month i will wake up in the middle of the night and feel really sick for an hour. Don't know what that is.
Yea doubt its kidney faliure (although it does run in the family) as I think I would have had more kidney pain or other kidney related symptoms.
