My child's receives mtx shots and I would like to know if there is a blood test to monitor side effects of this drug? I noticertainly that her hands were quite warm after the shot was given. She does complain of being gassy a day later. She began drinking the pediasure peptide last week. Thank you guys for recommending this. She is tolerating this better than previous drinks. Also, have any of you tried the scd diet with your kids?
