Strange kind symptoms and conditions

I began Doxy in Sept of 2007. The first week into it I noticed the roof of my mouth felt strange, kind of rough and sore. I attributed it to the drug and figured it would go away once I was off of it. I began to get a very sore tongue which I attributed to candida....it was a little white too. I was on the drug for five weeks and the mouth symptoms never went away, just went on to become a chronic burning tongue and mouth. Scalded feelings in the mouth as though I had slurped boiling hot coffee. Also, noticed I began feeling very tired and melancholy on the drug....those symptoms have never really gone away. It's been nearly a year and I have tried multiple remedies for my mouth and nothing helps. Has anybody else had the burning and inflammation feeling in their oral cavity. It shows no outward signs.

I have been taking Lisinopril for 7 months. The cough started after 2 weeks, so I went to a doctor thinking I hada strange kind of flu. I sometimes can´t speak after coughing, seems that my vocal chords have an irritation. This doctor prescribed me antibiotics, as it seemed that I was experiencing some kind of pneumonia. I was fine for 2 weeks, but again I began with the dry coughing, specially at night and when running a little. After I visited my Cardiologist, he told me that my cough was a reaction to Lisinopril, so now he has prescribed me another medicine.

I have taken advair on different occasions for bronchial/asthma symptoms.
I usually take the 100/50...and had little problems...this time I was put on
250/50 and have had problems with my voice..almost a sandy feeling. It almost seems like I have a strange kind of spasm going on. After reading other postings, I feel sure this is the cause, as these sensations weren't there prior to taking the Advair.

Just wondering if numbness in extremities, particularly toes/feet, could be caused by Advair? I've had loss of feeling in my feet on and off since starting it almost a year ago. The past couple days most of my toes have been nearly totally numb.
