Feeling .... sick?

New symtpom leads to a new question. Lately I have been experiencing a run down sick feeling. Mainly in my head and chest, like the feeling your coming down with a cold or flu or just can't kick it. Hope that makes sense. This has been going on for weeks now but I am finally seeing a pattern between the worsening headache and the feeling. Does anyone else experience this? Has your dr mentioned anything? As spring is finally making an appearance and I am getting spring fever, this 'yucky' feeling is being quite a drag. I can tolerate the pain (although that seems to be worsening) and the tightness, but now I just feel sick and it's quite bothersome. Other than my drippy nose (thought it was csf but apparently not) there aren't any other symptoms of illness.

Thank you!
