calf stretching exercise and kinesthesia tape help

Detailed Answer:
Hello,
Thanks for writing.
I Dr.chugh, Orthopaedic surgeon. The problem you are having is medically known as tendoachillis bursitis that is inflammation at the site, it is very common. I hope you are medically fit (non diabetic) and have normal weight. In this earlier you start the treatment better the prognosis.
As far as treatment is concerned my advice for you would be-
1.Rest your feet. Limit or, if possible, stop daily activities that are causing your heel pain. Try to avoid running or walking on hard surfaces, such as concrete. Never walk bare foot that is put on your shoes as soon as you get out of bed.
2.Wear shoes with good shock absorption and the right arch support for your foot. Athletic shoes or shoes with a well-cushioned sole are usually good choices.There are special sticking tapes(kinesthesia tape) are available to reduce pain. 
3.You may use silicon heel cups to cushion your heel. Use them in both shoes, even if only one foot hurts.
4.The usual medicines you may have are Ibuprofen/naproxen to relieve pain along with tablet tendocare under medical guidance.
5.You may do exercises like toe stretches, calf stretches and towel stretches, several times a day especially in the morning. For towel stretches, you pull on both ends of a rolled towel placed under the balls of foot.
6. Use hot and cold fomentation (alternate hot and cold water, make sure you end with a soak in cold water).
In the follow up query you may send the x-ray picture of heel If done.

Hope this helps.Take care and I shall be glad to answer any further query.
