Suggest Remedy For Trigger Thumb

i have 'trigger thumb'. this i only knew about a couple of weeks ago. the doctor prescribed Arcoxia T 90mg and Prednisolone 5mg tab. can these medications acually rectify this condition?

are there any forms of massage that can be done to releive the pain and provide better motor function of my thumb.

it seems that the colder the enviroement the more the tendency for the locking of the joint. is this a true senario.
