Way back when I had only had my QH mare Lucy for a year, she took a stick 3" upward into her suspensory tendon and ripped the sheath surrounding it. Freak accident for her, as she was trying to get away from a rather obnoxious alpha mare in the field and slipped in the mud in the field as she spun.
Like you, she was on Pen-G shots for I believe, 7 to 10 days, developed an infection and it got into the senovial fluid surrounding the tendons, so we had to switch antibiotics, Lucy was on stall rest for over 4 months, a few trips up to Texas A & M for ultra sound treatments, then a lot of cold hosing, checking the senovial fluid till it was clean, therapy that I learned to do, and eventually she cleared up.
However, I can never ride her like I can her brother. I can lightly ride her, we have children on her, and light w/t/c around but if I work her too hard, the tendon will swell up. So, I wonder if this isn't the type of road you may be down. Just keep it clean, keep it from forming scar tissue and ask your vet about hand walking and moving around to keep it moving.
