Does 'pin Prick Sensations' On Skin Reduce With Time?

had a leg injury recently, for which the doctor had given me nervijen P. have had pin prick sensations ever since, which increase with some drugs like montelukast sodium. my neurologist has put me on rivotril and oxetol for 15 days. blood reports, nerve conduction test and EEG are all normal. Do you think these abnormal sensations will reduce with time ?
