what parasite causes lipomas. My radiologist says they er not exactly like lipomas because the fail to have the capsulated disc around the lumps of fat, but hardened lumps of fat are there in my legs and large behind the knee. They are not painful. Only behind the knee is sore if pressed more than slightly. The little ones all in my thighs are tiny and I think they re sore because they re touching my nerves. PLEASE HELP. MY DOC IS BAFFALED AND SO AM I! I think I may have a parasitic infection. I have IBS, leaky gut syndrome, food allergies and intollerances and had a lower back spinal injury 4 yrs ago herniated from L1-L5 but now better. Did suffer Meralgia Parastheica from compressed nerves not sure is from tight hip flexors or lumbar injury CT and MRI could not tell where it was coming from.
