There can be many causes of lung nodules commonest being infective like in TB, fungal infection etc. Then there is a long list of many other causes. However no lung nodule is to be neglected. Hence, I advise that you consult a pulmonologist who can examine you and can correctly interpret the cause and significance of these nodules.

The findings report states "small solid lung nodule smoker (former smoker) " . However, I've never smoked in my life. Mu father and grandfather both smoked all my life. Do i need to worry? The size is 4 mm and has remained that size for the kast three years.

Good day. I have noticed a strongish smell after urinating. The pharmacist said its either a fungal or bacterial infection. Diflucan was suggested, but that would only sort out a fungal infection not a bacterial?? i had been on antibiotics a while ago and my life is very stressful right now due to my mother being ill. In the past I would use Diflucan after antibiotics to get rid of the candida which antibiotics cause. NOw there is only a smell of the urine but no actual discharge.

I have a dermatology issue. The skin on my fingers crack. I live in Maine and have suffered from chap fingers all my life. But now it seems to affect my thumbs. During the year, when my hands are clear. A calous will appear. And the skin will peal, and the layers of skin will continue till they eventually bleed. Right now both thumbs are affected.
