While not a smoker, I'm almost positive it's the
stress from stopping
smoking which has made your blood pressure go up. But first of all, let me CONGRATULATE you for having stopped and having the courage to not even think of going back. Someone very close to me took years off her life because of smoking and also because of being unnecessarily nervous due to fears, etc.
Ironically it was FEAR and stress which made her pick up smoking after having valiantly tried to stop. And only because of the unfounding fear of another smoker who told her the very stupid story of someone having gotten cancer six months after quitting!!!
SMOKING and STRESS is what has her hooked up to
oxygen tank or air concentrator (electric oxygen provider) 24 hours a day. And a couple of people in her immediate family monitoring her salt and acid food intake; caring she doen't dehydrate; propping her pillows; watching for excess carbon dioxide in her blood. And making sure no single thing alters her mood, whether the singlest bit of bad news or the overexcitement of any new event!!!
Remember that with lung disease, such as
COPD, comes other "partners", for example, CHF. This combination of lung and heart defficiency destroys person completely.
Regarding blood pressure; she suffered it throughout her life and is currently on medicines for it as well. If your doctor feels your blood pressure needs meds, then you do have to take them. It might be related to the cessation of smoking. It may not. But don't leave it untreated. Also keep yourself busy with as many things as possible, such as by incorporating hobbies to your daily life. Dancing, reading, knitting, writting, painting, listening to music, playing an instrument. Anything will help you in not wanting to smoke, and will calm your nerves beyond your belief!!!
If you're calm, there's zero stress. With less, or no stress, there's no
high blood pressure. Unless there's another underlining illness. CONGRATULATIONS, AGAIN!!!
