Terrible headaches with COPD
I have COPD – 68 years old – don't know what stage COPD yet – find that out next month – but, I would guess stage 3. Within the past 3 months I started having terrible headaches especially when coughing. Nothing, other than lortab, seems to help. Headaches/migraines last all day – seem to disappear when I go to bed – after rising in the morning the headache comes back after I am up from bed about 45 minutes. Coughing, which I do a lot and very deeply to clear mucus, feels like someone is stabbing me in the head with knives and makes the headache/migraine even worse. Is this or could this be too much CO2 in my blood and a lack of oxygen in my blood? if so, can this be helped. I am a 56 year smoker trying to quit. I am on Chanitx and have reduced smoking to 10 or less per day…will stop completely in a short time.
