Tendon pain in the middle of the foot may be due to inflammation of the plantar fascia. Inflammation of the plantar fascia is directly related to chronic strain and cold, resulting in inflammation of the plantar fascia or tendons, which manifests as tingling pain on the bottom of the foot, especially when weight-bearing. The most prominent manifestation is that the patient feels sudden and severe pain in the foot after rising in the morning and bearing weight for the first time, which is due to the pain caused by the increase in plantar fascia pressure due to the sudden weight bearing after the plantar fascia pressure has decreased during the rest period. Attention should be paid to reducing activities and weight-bearing. In addition, clinical treatment with non-steroidal anti-inflammatory drugs can be combined with herbal scalding, and herbs that warm the meridians and activate the blood, like mugwort, henbane and cinnamon, can also be chosen. For the inflammation of plantar fascia, you can also apply topical creams with good effect, like flurbiprofen gel paste, all of which can slow down the inflammation of plantar fascia and relieve the pain.
