Thanks for your query at DoctorSpring.com
As the platelets are important in Clotting mechanism, their increase or decrease can affect the blood clotting mechanism.
In your case, first get a Colour Doppler of the affected lower limb to exclude vascular problems or any collection in the affected area.
If it is normal, then you have to consult a Neurologist and get Nerve conduction studies and ELECTROMYOGRAPHY (EMG).
Till then, please use the medicine prescribed by your doctor.
Keep your limb in a comfortable and relaxed position.
Get your latest Platelet levels.
Hope I answered your query. If you have any questions, I will clarify further.
If you come back with above reports, I will explain.
