Knee Pain During or Post Workout

Don't ignore the pain.  Knee pain during or post exercise can be the indication of an injury, which if not handled properly could get in the way of your workouts!

First things first.  You need to book an appointment with your doctor and ask them to diagnose & provide a treatment plan.

Consistent burning in the knee could be:

-  Knee Sprain

-  Tendinitis and Bursitis

-  Meniscus Tear

-  Arthritis

-  Patello-Femoral Syndrome

You should look to modify your program to avoid further cause any injury, rest and ice as a precaution / to reduce swelling.

One common problem people suffer from is  "Iliotibal band Syndrome (patellar tendinitis and bursitis) can all cause a burning sensation in your knees during and after working out.  Burning typically in the lower portion of your kneecap.  Possibly due to over training (running is also a common cause). 

Cause

The iliotibal band is a fibrous tissue that runs from your hip bone to the bottom of your knee. This band of tissue becomes so tight from overuse that it rubs on the outer portion of your femur, which causes the burning sensation. If you're a runner, you're most susceptible to this injury if you have a leg length discrepancy, excessive foot pronation or are bow-legged. Using incorrect form while working out and running on a rigid surface can also increase your risk of iliotibial band syndrome and patellar tendinitis. Patellar tendinitis is an overuse injury that's caused by one or more of the tendons that connect the quads to the shin bone becoming inflamed. Bursitis is caused when the bursa, small sacs of fluid that help reduce friction on the knee, become inflamed. Bursitis can be caused by overuse, an infection, trauma, rheumatoid arthritis or gout, the PubMed Health website notes. 

Treatment

Knee injuries are initially treated by resting the knee, icing the sore area, compressing the injury and elevating your leg above heart level. Corticosteroid injections are sometimes used to relieve pain of the knee joints. If bursitis is causing the pain, a doctor may draw out fluids from the bursa and inject corticosteroids. An over-the-counter, non-steroidal anti-inflammatory drug can relieve knee pain in most cases, but if your pain is severe, a doctor may give you prescription-strength painkillers. Non-weight-bearing resistance exercise for the muscles surrounding the knee can promote healing of knee problems. The pain from patellar tendinitis can also be treated with ultrasounds and electric muscle stimulation. Surgery is only necessary for severe and persistent knee pain from these conditions. 

Prevention

A regular strengthening and stretching regimen is needed for the muscles surrounding your knee. Strong muscles will help support your knee while working out so the area will be less prone to future problems. Increasing the flexibility of the muscles, ligaments and tendons of your knee will also reduce your risk of an overuse injury. While strengthening and stretching your leg muscles, pay special attention to your quadriceps and hamstrings. To avoid iliotibal band syndrome, stretch your hip flexors, lateral thigh and inner thigh.
