Never been a sound sleeper. I average around 4 -5 hours per night and that is usually interupted by noise or pets. I have had a slight cough over the last few weeks. Thinking it is allergies from post nasal drip. No fever.

Are you taking some medicines?

Had a hematoma on the brain. The only med i tale is Lisinopril for blood pressure. Weight and appetitie are fine. Recently I have had a hard time breathing, either exhausted from stairs or pain in chest area when I breathe deep.

Increased sweating is related to head injury, but there can be many others reasons for severe sweating.
