Could my knee pain be attributed to my weight gain/plantar fasciitis?

I've had plantar fasciitis for close to a year and recently, my lower back and knees have begun hurting. I went from 230 to 258 in less than a year, partially due to my fasciitis and subsequent lack of running and exercise. Could my knee pain be coming from PF or weight gain? Or a combination thereof? My lower back pain, could that also be caused by the two? I'm 5'8 and otherwise healthy 25 yr old.
