That is what started all this mess., I to has lost a lot of weight, I was just beginning to add workout to the program, and I started to have knee swelling and stiffness. So I stopped working out, then I started falling, I fell of a porch and messed up my knees, then the stiffness got worse, and the weakness continue. Went to physically therapy trying to strengthen my legs , pain just got worse, of course I gained a lot of weight back, from all this mess. I don't have RA, but I do have Osteoarthritis, please be careful and continue to work out , swimming is good for weakness and it won't hurt your joints

Hi! So sorry you are feeling weaker. Please consider talking to your doctors. For me, yes periodic muscle weakness has been an unfortunate reality. Was terrified that it was something else. Probably took four or five months of methotrexate to not feel like I was weakening by the day. Hope the issues abate and you get relief.

I have a great appetite and eat well but I have lost 30 lbs in the past 18 months without trying along with muscle mass. I am a skinny 6'4" 160 lbs.

I was told both the RA and some of our meds can cause muscle loss... talk to your dr as some of the RA meds might help more than others, and physical therapy helped me in the meantime. Now I have a plan from PT of how to help counter the issue. Hope you are feeling more like yourself very soon.

Thanks guys, I will definitely talk to my doctors about it.
