Use heat: tiger balm or something similar and also perform the following stretches:
Lie on back, pull one knee to the chest, hold for 10-15 seconds and then switch legs, then do both at the same time
Stretch your lats by holding onto a door frame with a flat back bent at the waist and tilt your hips to the side opposite to the hand holding the door
Those two things combined should help. Let me know how you get on.
Don't call it a comeback
