Why it happens

Sports activity, uneven surfaces, obesity and a previous ankle injury are the usual risk factors. The foot absorbs several times body weight with each step through the plantar fascia, the Achilles tendon and the ligaments of the ankle — sudden loads sprain the ligaments, repetitive load outpaces the tendons, and old injuries wear the joint.

How Dr. Kiruthika assesses it

Physical examination, X-ray for bone injuries, and ultrasound or MRI for soft-tissue injuries — ligaments, tendons, fascia and nerves are all graded on ultrasound in the same visit.

Conditions treated

Ankle sprain — ATFL, PTFL and CFL ligament injuries

A twisted ankle stretches or tears the outer ligaments — the anterior talofibular (ATFL), posterior talofibular (PTFL) and calcaneofibular (CFL). Most sprains heal with bracing and rehabilitation. Persistent pain or instability suggests a partial tear: ultrasound-guided PRP supports ligament healing, with a balance programme. Referral for reconstruction when instability persists.

Achilles tendinopathy

Pain and thickening of the Achilles tendon, in the middle of the tendon or at its attachment. An eccentric loading programme is the foundation; ultrasound-guided PRP is effective for chronic cases that have not responded to standard treatment.

Retrocalcaneal bursitis

Inflammation of the bursa between the Achilles tendon and the heel bone; pain and swelling at the back of the heel, worse with shoes. Ultrasound-guided bursal injection, placed away from the tendon.

Tendinopathy of the ankle tendons

The tendons around the ankle can become painful under repetitive load. Ultrasound shows the tendon structure; treatment is a loading programme, with ultrasound-guided PRP when healing stalls.

Plantar fasciitis (heel pain)

Degeneration of the plantar fascia where it attaches to the heel; sharp pain with the first steps. Calf stretching, insoles and footwear first; ultrasound-guided PRP into the fascia for persistent pain.

Morton’s neuroma

Thickening of a nerve between the toes, usually the third and fourth; burning, tingling and a feeling of a pebble under the forefoot. Wider footwear and metatarsal pads; ultrasound-guided injection around the nerve.

Post-traumatic arthritis

Wear of the ankle joint years after a fracture or repeated sprains. Ultrasound-guided joint injection — hyaluronic acid or PRP — and supportive footwear.

Treatment options, least to most invasive

  1. Self-care — rest, ice, compression and elevation (RICE)
  2. Medical — pain medicines and physiotherapy
  3. Interventional & regenerative — ultrasound-guided PRP or stem-cell–based therapy for ligament and tendon healing
  4. Surgery — for severe instability or fracture. Referred directly.

On the day

Ten to twenty minutes under ultrasound guidance; PRP about forty-five minutes including the blood draw. Walk out in your own footwear; reduce running and jumping for two weeks after a tendon or fascia injection.

Questions patients ask

How long does an ankle sprain take to heal?

Mild sprains may heal in two to four weeks; severe ligament tears may take months.

Can PRP help Achilles tendon problems?

Yes — PRP is effective for chronic tendon injuries that don’t respond to standard treatment.

Why does heel pain hurt most in the morning?

The fascia tightens overnight and is stretched suddenly with the first steps. Stretching before getting out of bed helps.

I have diabetes — does that change anything?

Yes. Foot problems are checked more carefully, healing is slower, and any skin break is treated seriously.
