Periostitis Periostitis, also known as periostalgia, is a medical condition caused by inflammation of the periosteum, a layer of connective tissue that surrounds bone. The condition is generally chronic, and is marked by tenderness and swelling of the bone and pain.

It can be caused by excessive physical activity as well, as in the case of medial tibial stress syndrome (also referred to as tibial periostalgia, soleus periostalgia, or shin splints). Congenital infection
Medial plantar nerve ball of the toe. It will be observed that these digital nerves are similar in their distribution to those of the median nerve in the hand. Medial plantar nerve The medial plantar nerve (internal plantar nerve) is the larger of the two terminal divisions of the tibial nerve (medial and lateral plantar nerve), which accompanies the medial plantar artery. From its origin under the laciniate ligament it passes under cover of the abductor hallucis muscle, and, appearing between this muscle and the flexor digitorum brevis, gives off a proper digital plantar nerve and finally divides opposite the bases of the
