Respiratoric
- Hoarseness
MN of the throat often causes hoarseness and prickly sensation in the throat, occasionally had a cough with sputa, but there is usually no pyrexia or dysphagia (3). Meanwhile, patients with MN of the bronchi often had a cough with sputa (20). [fomm.amegroups.com]
Gastrointestinal
- Constipation
MN present on intestinal tract often causes stomachache and constipation (21) and MNs of the oral cavity are usually painless but may interfere with eating or cause oral and maxillofacial deformities (4-7). [fomm.amegroups.com]
- Dysphagia
MN of the throat often causes hoarseness and prickly sensation in the throat, occasionally had a cough with sputa, but there is usually no pyrexia or dysphagia (3). Meanwhile, patients with MN of the bronchi often had a cough with sputa (20). [fomm.amegroups.com]
