Yes, I have both. The OA is in my knees and is very painful. I take Excedrin and rub on Aspercreme , use heating pad and hot baths. I am managing, but only just. I walk even though it hurts because If I don't I won't be able to at all. I have RLS day and night, I take ropinerole and gabapentin for it. Sometimes it works quite well and sometimes not. My issue is when my legs hurt and I can't move and RLS kicks in and I need to move. I get so tired, can't lie down. Any movement that involves bending the knee is out. Also my legs swell and I need to rest them, but I can't. So please share any ideas, thoughts, sympathy , what ever you've got. Thank you, so so glad you are here to vent to.
