Psoriatic Arthritis
"I&#039;m curious can methotrexate cause weight gain I rarely eat anymore except for the three days leading up to my next dose I&#039;m fatigued, headaches, weak food causes acid so I must be very careful that I eat bland foods with little fat and since I&#039;ve only been on it for 5 weeks I&#039;m in the MORE PAIN part of getting used to the meds part of all of this.  But how could I possibly feel like I&#039;m gaining weight when I eat next to nothing 4 out of 7 days and club crackers as my only snack"
