Nightmares in adults are often spontaneous. But they can also be caused by a variety of factors and underlying disorders.
After going through your query, I would like to comment the following:
1. You seem to be suffering from GERD (Gastro esophgeal reflux disease, Bronchial asthma
& systemic hypertension
2. Your asthmatic symptoms also require the control of your reflux disease since reflux disease is known to be a trigger of asthma symptoms.
3. As for your night sweats
, there is a possibility of it being related to simvastatin
. Please consult your physician regarding this.Dose modification or change of medication may be done if it is the cause.
4. Also other causes include infections like tuberculosis
. But in absence of other symptoms these are unlikely causes.
I do hope that you have found something helpful and I will be glad to answer any further query.
