hi shweta,
go 4 some VMO muscle training,it assists to clear the swelling.it can be done with faradic stim also.
in my opinion IFT(dipole vector) is good 4 pain relief.
Ergonomic advice is most imp,avoid squatting,etc
go 4 hams stretching & u could also go 4 gr1-2 mob to relieve pain.
hope this helps,
regards
