Lucy, an english smooth, 6 year old female pig.
2 - brief description of signs leading you to suspect arthritis
Sitting in a hunched position, puffed out coat, not moving as much, weight loss.
3 - diagnostics done and the results
I was concerned that it was something to do with her tumours (see below). The vet manipulated her hind legs and massaged the lumbar spine and found she was in a lot of pain. They took blood for a separate purpose (to check electrolyte levels because she is on hydrochlorothiaside for calcium in the bladder) and found the levels to be within normal levels.
4 - treatment, med and dosage
Metacam dosage was increased from 0.3 x1 a day, to 0.6 x1 a day.
PT was recommended on the hind legs and lumbar spine
5 - results of treatment
I've noticed a different in Lucy; she is 'lying down' (relaxing) more, spends less time hunched and puffed and seems brighter.
6 - other med issues
Lucy has a number of masses (a tumour on the liver, a tumour on the spleen and a mass on the ovaries).
She has some alopecia after a bout of mites in the household.
She has had recurrent bouts of UTI
She has problems with calcium deposits in the urine.
