Hi mhewitt

I realize that it could maybe take longer than that for something to 'heal',......"Trigger Points dont tend to heal, they will diminish put will not disappear until Direct Pressure is applied for 30secs to a few minutes until the pain has ceased.
Once TrPs are deactivated you will need to change/alter your movement patterns so the trigger points dont reoccur.
As an example i have a left side low back pain after running..that is corrected by Tigger point therapy/massage/stretching..but i also need to strengthen certain muscles in my glutes to prevent the problem happening again. Try this website .
