Hello,
Plantar fasciitis is an inflammation of the envelope that surrounds the heel. Usually, the pain occurs in the morning and during the day when there is an effort on the feet, so it is difficult to know if it corresponds to the description you gave. Note that pain in the form of burning, tingling, numbness or stabbing is not usually reported for fasciitis
Since plantar fasciitis is an inflammatory condition, it is possible to take anti-inflammatory medications such as Advil, Naproxen or Voltaren (only 1 of the 3 at a time). To know the dosage and which one would be the best, it would be relevant to go and consult your pharmacy who, by asking you a series of questions (ex: duration/intensity of pain, allergies, previous illnesses, etc.) will be able to propose a personalized treatment
In addition to medication, it is important to ask questions about your shoes and your posture, which are often the cause of these pains. For example, ill-fitting shoes that do not absorb shock or that do not support the arch/heel will increase pain. Insoles can help. Otherwise, it is recommended
- Decrease or even stop putting weight on the foot REST.
- Massage the plantar fascia regularly to loosen it up
- Apply ice 10 minutes/hour after physical activity or at bedtime.
