My mother has been constantly getting cold(stuffy nose&slight fever ) in intervals(when she is getting in contact with dust whule cleaning).She also feels dizzy when ever she lies down or when she suddenly wake s up in the morning.dizzines was quite severe one night when she couldn't even stand but felt calm after a while after eating a chocolate.Today she also had a headache.We consulted a doctor a while back when she was having just colds and everything was normal.
