LCL Rehab

Hi guys, Im in the middle of rehab from a Lateral Collateral Ligament tear (I think, Ive not had it properly diagnosed).

Quick question - After 30 days rest, Im now 'pain' free and swelling free on the affected knee, but the knee sometimes feels stiff and I sometimes get a mild 'ache' in the area just below my LCL and at the top of my shin, down the outside of my knee.

Is this normal to feel this at my stage of rehab?

Thanks,
