This could be a condition known as PLANTAR FASCIITIS
.Do you feel that the pain is more in the morning on taking the first few steps after getting down from the bed? I would advise you to give your legs some rest. Stop the activity which triggered the pain.You could try using supportive aids
like arch supports or heel cups. Do Achilles tendon stretching exercises ---- Support the toes at the edge of a step. Hold this position for 1 minute followed by a brief period of rest. Do this five times .This should be performed 3 -5 times a day. Dynamic stretches of the achilles tendon can be done by rolling the sole of the foot over a cylindrical object like a can or a chappati roller. Do this 10 times followed by rest and 3 repetitions. If the pain is bad you can take(if no history of drug allergy
) anti inflammatory drugs like Ibuprofen
400mg 1-1-1 for 2 days (after food). Ranitidine
150mg 1-0-1 for 2 days.
Please visit your doctor if not better in 2 days
Get well soon
