I Had A Partial Colectomy 3 Months Ago To Remove

I had a partial colectomy 3 months ago to remove colon cancer. The laproscopic incision got infected and became septic. It led to me having to intubated and sedated in icu. I was given antibiotics to clear up the infection. It led also to toxic encephalopathy. I have been in a rehabilitation center, regaining my strength and memory. I have recently had pain where the cancer was cut out and bloating in my stomach. Is this part of the healing process?
