I have had pain in my wrists/thumbs for the past 4 mths since my son was 2 mths old. Been to the physio today who diagnosed it as deQuervain's syndrome. They often see it in new mums. Is result of lifting him. Am delighted to now have a name for it as can look it up. Need to wear some thumb splints. Also ibuprofen gel. Have been having acupuncture which is helping a bit. Hope this is helpful for anyone having similar symptoms.
