"I feel good, no limitations, no effects of anything," Collmenter said.
Collmenter was placed on the disabled list Aug. 10 after being hospitalized with stomach ulcers.
"Other than the few days I was in the hospital with it, there was no pain, no serious aftereffects," Collmenter said. "It took a few days to get my energy level back to normal, but that was it."
The last couple of weeks, Collmenter has been throwing at the team's Salt River Fields complex.
"It was weird being on the DL, but not having to rehab anything," Collmenter said. "Everyone else there was working on something, and I was just throwing."
Collmenter will have further tests performed on his stomach following the season.
