Hi Neel,
You know we never know how our blood vessels look inside the body. We can for example have enlarged veins round the lowest part of oesophagus. It is very dangerous if these start to bleed and the platelets are low. We can have weak spots in the blood vessels in the brain and easily get a brain bleeding and so on.
There are tests for platelet function like PFA-100:

When we have low platelets we should try to avoid everything that can decrease platelets. Painkillers will often be dangerous. Here is a link about drugs and food that can decrease platelets or increase risk for bleeding:

Then you have perhaps seen that some members are taking Promacta/Revolade or Nplate for their low platelets with positive results.
Kind regards
