Sir/ma'am Since, a week, My 2.3 year old son complains about something strange feeling in right hand mostly waking up in morning or after nap. Sometimes, he says Dard ho gyi, theek karo haath ko, like this, as he can't describe what he is feeling. But gets well by himself after some minutes. Even he cried one time that he has pain then got well within minutes. This is the case mostly after waking from sleep but sometimes other time also. What's the reason. Please reply.
