Rheumatoid Arth. & Part Time Wheelchair

I am 20 years old & when I was 14, I was diagnosed with Juvenile Rheumatoid Arthritis. For the pasted few years, it has been attacking, severally, my knees & hips. I’ve been debating for a while, if I want to get a wheelchair to use when I go out with my fiancé. We love going to the zoo in our state, walking around the mall, etc & I can usually walk about 10 feet & then sit down for 10-20 minutes & rest & then start walking again. I only want to use it when we go out & I’ll be walking a lot. So, my question is, those of y’all who are part time wheelchair users: does it help with your pain? What kind of wheelchair do you use? How do people treat you if you stand up or walk a little bit? Is it more of a hassle then it is helpful? Any input is appreciated!
