question: What are possible causes for multiple lumps/bumps that are under the skin and between the knee and ankle? There is no irritation or swelling, no protruding out of the skin, only sore when pressure is applied, x-rays did not show anything attached to the bone and MRI was inconclusive. Orthopedic stated it was not related to shin splints or shin splint lumps. What are my next steps? Who should I take my 19 year old daughter to for a diagnosis? Thank you in advance for any help that you can provide.
