How about numbness or tingling along anterolateral aspect of the leg ! How about muscle power of toes abduction and adduction ? Yes , the nerve can be trapped near the head of the fibula , I saw some drivers with this complaint from just resting their left leg over the car door long times espicially big cars . The point is more stress and pressure over the nerve could detriorate it , the nerve just needs chance to recover ( regenerate or rewiring if there is real problem ) , give it chance of rest for one week by :
-Stop sleeping over it
-Stop pressing it by your thumb and hand
-Stop over excerising it , because more muscle contraction means more stress
-Stop flaring -up pain and referred symptoms
-Calm down , practise some breathing
-imagrey ex. could help
-Neural Mobilization gentle of great value
-after the week you can begin some gentle bicycling
-just simple active motions are appropriate


Testing if there is weakness or not can be through testing if you can walk on toes , and if you can walk on heels ?!

That is much ideas
Best luck for you
