You have already started treating your bursitis, by understanding the cause of Bursitis, so you can actively do things to reduce the stress and friction on the Bursa.
We advise you see a Physiotherapist to be assessed for causing factors, and to be advised if a cortisone injection maybe helpful.
Resolving or treating Bursitis must involve technique to reduce the stress and friction on the Bursa like massage and specific stretches (Please Note: Some massage and stretches will make it worse). Once the ‘irritating stress’ is removed with hands on therapy, postural correction, strengthening, then postural control exercises are required to maintain this improvement.
This will allow your bursa to do its job and absorb friction and compressive forces without abnormal or excessive friction and stress and you will stay pain free.
