Hello I am 72 and had colon resection surgery in January for Diverticulosis also . Took me 3 months to recover but I am a slow healer . It left me with scar tissue on my left side. It is very painful . It is now August and I am still dealing with it daily . Doctors told me same thing they told you . My mistake was not asking a lot of questions. It is a very scary operation . I then had to have Gallbladder surgery on June 9th . Still having bad parents n on right side where surgery was done !!! I have been in constant pain since January 27th and I have vowed to never have another operation . Have appointment with Gastric Dr and Pain Management. So tired of dealing with the pain no kind of quality of life but thankful to God for His guiding hand everyday ! Hope you make the right decision. Wish I could be of more help to you . It is a tough surgery at least it was for me !!
