Welcome to healthcare magic for your health concerns I am Dr Fahim, and I will be looking into your problem . . . I have gone through your question and understood your concerns. Bakers cyst is a benign swelling of the semimembranosus or more rarely some other synovial bursa found behind the knee joint. It might results in discomfort while flexing the knee joint but certainly not associated with lumps on the calf and shin and that too half a dozen. There are many differential diagnosis of lumps on shin and calf which includes lipoma, sebaceous cyst, boils, moles etc, You need to see a general surgeon who after clinical examination, will be able to diagnose the case and will further guide you. I hope my answer will help you. Do rate my answer if you like it Regards
