Madam You may have to consult an Orthopaedician for clinical examination

Dear Madam, Your question doesn't tell me how the knee pain started. But the description of pain and morning difficulty and need to stretch tells me that along with knee pain you also have plantar fasciaitis. You need to see an acupuncturist for both these conditions , as acupuncture can cure both in a short time. In Pune you can get this therapy at home also through my hospital .
