I haven't had a solid bowel movement in a month it's always like in pieces or mushy or diihrerra?

Go to MD: Lots of causes inluding diet, inflammation, parasites, viral or bacterial infection, tumor, other. Can't tell here-no details given. Even if details of history, etc. were available, you need an in person (not virtual) doctor visit.

Constipation:: You waited a month to ask this question? Use OTX Miralax (polyethylene glycol) and immediately consult a GI expert.
