Thanks for your query.
Nose bleeds,bruising,skin spots all can be ascribed to a low platelet count
of 92 thousand.
Platelets (thrombocytes) are colorless blood cells that play an important role in blood clotting. Platelets stop blood loss by clumping and forming plugs in blood vessel holes.
If for any reason blood platelet count falls below normal, the condition is called thrombocytopenia
Normally we have anywhere from 150,000 to 450,000 platelets per microliter of circulating blood.
He needs further blood work to find out the cause of low platelets.
in the mean time he should avoid contact sports,intramuscular jabs,and aspirin
Hope I answered your query.
Will be happy to help if you have any further doubts.
