I've had hard stool blocking my colon for many months and nothing seems to work to completely clear my entire large intestine. what can i take?

Evaluation needed...: Before you contemplate long term laxative dependency, seek medical evaluation--rule out metabolic causes of constipation (e.g. Low thyroid or adrenal conditions), distinguish slow versus normal transit constipation, consider a primary rectal dysfunction that may be treatable with biofeedback, check for structural pathology or extrinsic impingement, or intermittent ileus (e.g. Pseudo-obstruction).

Osmotic lax and DSS: Miralax (polyethylene glycol) and DSS (stool softener)
