No, but I do think my immunity is low.

My dad has felt like he's had sinus issues/cold-type symptoms for what he said at one point "has felt like the last several months." So mayBE??

I usually get a headache do to the change in medication. I get a slight headache almost everyday. Not sure if it is PD but that's what the doctor told me. Hey he can be wrong!

If you mean a slight runny nose, then yes it can be PD, is for me.

Were you started on any medication? Some drugs, like Azilect, Requip and Sinemet can contribute to nasal congestion.
Due to possible drug interactions with Azilect, decongestants should not be used!
Although my hubby is no longer on Azilect, he was able to take Allegra to treat his runny nose.
This is not a true cold, just rhinorrhea, although allergies can cause the same symptoms.
