Hi there yeh it can cause swelling, and at times painful. Retreived this for some info. Hope i got the correct one. lol

Inflammation is the most common reason for muscle pain and aches. Any time that major inflammation exists ("strep" throat, hepatitis, cancer, lupus, acute heart attack, etc.), signs and symptoms often include fevers, sweats, chills, fatigue, weight loss, and various muscle aches, pains and weakness. These non-specific, non-diagnostic symptoms are signs of your body's inability to cope with whatever process has overwhelmed it. Because lupus is an inflammatory disease it may cause any of these problems. These myalgias are a secondary part of the overall disease.

Lupus cerebritis is lupus of the brain. Alot of times it affects your balance and sometimes with your walking. You may have seizures as well

Yes it does. My body hurts so bad at times, Even a hug hurts.

For most people the DX of other forms of lupus will turn to SLE in their future,with the immune system already weaken fight off other auto-immune disease's can be harder. SLE is the mother load of lupus,it involves every part of your body.

Yes, I keep inflammation all over leg, arms, wrist, hands, ankle and foot.
