It's possible you have Raynaud's, which mainly affects hands and feet. I've had Raynaud's for years, long before my NTM and Bronchiectasis diagnosis. I would report your symptoms to your doctor to be sure. There are two types of Raynaud's: Primary Raynaud's phenomenon has no known cause. It is the more common form of the condition; Secondary Raynaud's phenomenon is associated with another underlying medical issue, such as RA, lupus, or scleroderma. Factors such as exposure to cold temperatures or certain chemicals may also be linked to this form. The secondary form is less common but typically more serious than the primary form due to damage that occurs to the blood vessels.

I have Secondary Raynaud's, likely stemming from my RA and Scleroderma. A simple blood test can determine if Raynaud's is your problem and what type you have.

I have found that the older I get, the more Raynaud's bothers me, even in the summer. I can drink a glass of cold water or iced tea, and my hands will turn white and then blue, almost black. I've learned how to control a lot of the triggers that set the Raynaud's into action. I take a light jacket into the grocery store, even in the summer; I drink almost NO cold liquids, and wear long sleeves or a sweatshirt in the summer so my husband does not swelter with our air conditioning settings at a higher temperature.

Your condition could be related to the medication or, possibly, Raynaud's. It might be wise to speak to your medical team for their advice.

Good luck.
