What Does Fusiform Thickening Chronic And Acute Partial Tear From The MRI Suggest?

Hello, I suffered a parial tear of my left achilles at work. OJI clinic misdiagnosed as sprain. No imaging done. I continued to work 40 hrs week (work for airline, on my feet and walk 3+miles per shift) In Nov the pain in my achilles became acute. I finally got MRI thru OJI physician. Shows fusiform thickening chronic and acute partial tears. Some are old, others are newer. Spent 7 weeks in boot / crutches. Now no improvement in lump on achilles, stills burns and hurts if I use it while in boot. I am pushing for surgery (topaz ??) and docs keep want to see what it does . Am I in line wanting to get the achilles cleaned up so it can start to heal normally? I have scar tissue built up around the original tears and it feels like constant pressure in the tendon area. PRP has also been mentioned, I do not know much about it for Achilles injury. I am sure the six months of continuous injury is creating further problems.
