I have been having a pain in my left leg particularly when i have to pray and put the two leg in a cross linkage position . it began 5 months ago and through this priod i wanted to lose weight and i had a 14 kilos loss over the 5 months but without good diet. And i used to play football frequently for the last year and sometimes i had to put NSAIDs to my legs avoiding pain during playing . i have done an blood examination and the result is neuropenia and lymphocytosis .what would be the cause?
