Seems I am on here from time to time with a possible new symptom. But, when you have a disease, you often wonder about any new changes in your body. Years ago, I had migraine headaches. Probably suffered with these headaches from the age of 12 to 35. Then after age of 35, the migraines seemed to greatly improve. Until just recently. Now, I am experiencing the migraines more frequently. Maybe few times a month. Always usually a warning before these headaches....blurring vision or seeing small flecks of light. This will usually last about half an hour. Then, the migraine starts. But, tonight was different. I saw the blurring vision or small flecks of light for about a half hour. Only this time, the migraine did not happen. Been having problems with symptoms of COPD of course. Part of the disease I know. But, there has been indications for several months, that my oxygen level has been dropping. Could these increase in migraines after years of not having them, be another symptom of something to do with COPD? I know the first time I saw my pulmonary doctor, he asked me was I having headaches. Just wondering if headaches and blurred vision returning, is part of oxygen level possibly dropping. Thank you.
