I still carry a purse but did switch from my prefered long handled/hanging by my hip style to a short handled/over shoulder & under armpit style (what most women would loop over a forearm or carry by strap). I have to have a purse to carry my walet, tampons, wee brush (long hair), w/c placard and bathroom supplies (thank you leakage...). I use two forearm crutches and AFOs and just found the short strap style fits well under my armpit & doesn't interfere too much with ambulation. If it is a really bad day my dear husband just carries it (he usually has me carry his keys keys anyway...).
Gotta love a man who is fine with carrying a bright purple Dooney & Bourke bag!
