Hi, I am experiencing pain running from my groin area, especially on my right side, generating near my lymph node in the inside of my left groin area, that runs down into my leg.....it s not a sciatic pain.....I am also experiencing cramping in my legs, like the back of my hamstring and cramping in my calves? Also, a lot of pain in my joints especially my knees....Do you have an idea what would cause these symptoms? Thank you
