Hello,
Your headaches could be a result of the shift of hormones due to your systerectomy. Are you taking HRT at this time? I had a hysterectomy and had the same problem with headaches. I took the very lowest dose of premarin for about six months which helped not only with the headaches, but with the hot flashes.
Do you have a post nasal drip? Allergies? These cold explain the coughing. Have you tried taking Claritin? This may help.
Do you suffer from heartburn? Acid reflux can cause coughing.
