Newbie to the site. Please be patient. I have a 4 yr old female who has a history of limping. First limp (right front) appeared not too long after she adopted us two years ago, but was chalked up to boisterous horseplay with her sister. From her symptoms, it appeared to be a bruised pad because the limp would become exaggerated as the surface became more rough; ie: no limp on grass, carpet, tile or smooth cement, but very bad on asphalt. On Vet's orders, rested her and the limp disappeared. Now she's limping in the right rear - started early March. No obvious injury - just started limping. She has been vet checked twice (he did everything but twist her limbs out of the sockets with absolutely no reaction from her), literally xrayed from head to toe (absolutely no bone issues), put on total rest (just leisurely strolls through the neighborhood), and wears a TheraPaw when out for a walk - which is about the only time she doesn't limp.
Just prior to the xray marathon, and over a weekend, of course, she developed a sore neck. Crying out, couldn't/wouldn't pick up a morsel of food from the floor - OMG! (Her food stand is elevated 12".) Out of desperation and lack of sleep, I gave her plain aspirin (two tablets, 24 hours apart) and the sore neck went away, never to return again. The limp seemed to improve for about a week but has returned full force. Just within the past few days she started doing the three legged walk in the house, on tile, but not on carpet.
She has been on MSM and Glucosamine since Sandy Paws in March but no other meds. My Vet knows I'm not big on meds (would much rather find the CAUSE than treat a symptom), so he has not offered any.
My only other observation is that when she walks on asphalt (crossing streets on our nightly strolls), she looks like she's walking on shards of glass; v-e-r-y s-l-o-w-l-y and very carefully putting each foot down "just so".
I welcome any and all ideas!
