I'm a US Postal employee and have carried mail for 18yrs. I'm currently recovering from a stress fx of the 2nd lft metatarsal. I had and MRI that showed a partially heald fx. 2nd lft. metatarsal, bursitis 1st, 2nd, & 3rd intermetatarsal and a chronic high-grade partial-thickness tear anterior talofibular ligament & very high-grade near full-thickness tear of the calcaneofibular ligament. I've been off work for @ 4mos. & I've been currently doing physical therapy. I'm still experiencing significant pain with normal activity & my Dr. says it's okay to return to my full duties at work. Since doing my job caused my condition what will be the consequences if any of returning to those duties without being fully healed? I still have several years before retirement, what is the likelihood of future complications? Should I be considering a new position within the post office or a new line of work?
