i am having numbness on my left side of chest. i feel heavy just below my ribs on the left side. The numbness travels down upto my thighs and also behind my chest. Could it be due to some serious internal problem? Doctor gave me anti inflammatory and no effect. There's no pain , but just the numbness whcih i could feel. Felt it when i woke up in the morning, before 10 days and it's still there. Can someone tell which specialist i should see.
