I'm a Registered Osteopath in Croydon and one of my patients suggested I come on here to give you some advice.
First of all. These knee conditions are commonly called a Bursitis. They're due to either friction or infection of a Bursa, a fluid filled sack around joints that allows for tendons to run smoothly around the joint.
Housemaids knee or Clergymans Knee are the friction type. I don't need to labour on the reasons why as you guys are always kneeling down to paint! (My dad was in the trade too so I remember him having bad knees and arthritic hands!)
1st of all, get some good knee pads! And I mean good ones! This is your livelihood after all!
Then look for a manual Therapist. Obviously I'd suggest Osteopathy as I'm an Osteopath but find one who does Acupuncture as this really can work wonders with the massage and Ultrasound.
Bowen Therapy can be very beneficial and is entirely non-invasive for those of you that don't like being beaten up by Osteopaths!
I can't really reccomend Chiropractics as I've never found just manipulating the spine particularly useful!
Physios must be of the type that are hands on. Massage, Ultrasound, Acupuncture. If all they offer is exercise walk out! Waste of money!
If it's infected you need to see your GP for antibiotics.
Do feel free to email me if I can be of any assistance on your aches and pains!
