The Pros and Cons of Cortisone Shots For Tendonitis and RSI’s

Cortisone shots are one of the most common treatments that doctors prescribe for tendonitis conditions like tennis elbow and RSIs such as carpal tunnel syndrome. But do they really work?

I’ll address that question below, but to begin with, what is cortisone anyway? Cortisone is a hormone produced by the adrenal gland. It is technically a cortico-steroid (not to be confused with the anabolic steroids that bodybuilders often use), and it is essential to maintain proper function of your body. Aside from certain people who suffer from Addison’s Disease, it is naturally produced by every human being, so no one is allergic to it.

If you get a cortisone shot, you probably won’t be injected with the pure stuff. Instead, cortisone derivatives such as Kenalog or Celastone, which last longer and produce fewer side effects, are more commonly used. Also, there is usually a pain reliever included in the shot. People who suffer allergic reactions to the shots are generally allergic to the pain reliever rather than the cortisone derivative itself.

Cortisone can be effective in suppressing inflammation for short periods of time. This will provide some pain relief, but without addressing the underlying cause of the condition, the pain will return after the effects of the shot have worn off. Also, there is a limit to the number of shots that can be performed within a given time period, since animal studies have shown that cortisone can weaken tendons and cartilage in joints when over-administered via local injections. (This is not a problem with oral cortisone doses, which are absorbed by the body gradually over a period of time.) This possible adverse effect is more worrisome in younger people, as their joints and tendons are still healthy, so patients below the age of 25 especially are encouraged to exhaust all other forms of treatment before getting cortisone injections. With older patients, whose joints generally have already experienced significant damage, it is not as much of a concern. Also, certain tendons – the Achilles tendon in particular – are prone to rupture even when the injections are performed with the utmost care.

Inflammation, while often a useful physiological reaction, can actually hinder healing when it is present in excess. The idea behind a cortisone shot is that by helping to suppress unnecessary inflammation, it will thereby aid in healing. However, the most recent medical studies are increasingly showing that tendonitis, RSIs (tennis elbow and runner’s knee; carpal tunnel syndrome and related conditions suffered by data entry professionals) and the like are not actually caused by inflammation, but by some other mechanism — the most likely culprit being direct damage to, and/or fraying of, the tendon. This, of course, calls into question the entire rationale for the shots in the first place.

So why do patients report a decrease in pain? For starters, not all do – cortisone shots are reported as being effective in only about 50% of the people who receive them. For those that do experience relief, the most likely explanation is that the analgesic included in the shots has a temporary deadening effect on the pain. Also, placebo effects are powerful and can never be discounted.

While cortisone shots are a very effective treatment for certain conditions such as arthritis in older patients, there are serious questions as to their effectiveness when it comes to conditions like RSIs, tendonitis, tendonosis and the like. In younger patients and runners suffering from Achilles tendonitis in particular, it seems that there are more effective tendonitis treatments available, with a better cost/benefit ratio and far better success rates. Admittedly, cortisone shots are relatively inexpensive, easy to administer, and don’t take a lot of time. Further, they fit very well into the usual medical paradigm of addressing a condition rather than the cause of the condition. And, of course, doctors can monitor their use. But when you consider the discomfort of receiving an injection directly into damaged tissue, the questionable mechanism by which it is supposed to work, the coin-toss percentage of patients who report even temporary pain relief, and the possibility of potentially severe side effects, it makes sense to try other treatments first.

  1. Cortisone Shots For Tendonitis and RSI’s? Does this comes cheap?
    I’m suffering from posterior tibial tendonitis for a couple of years now and i’m finding a cure on how i can get rid of it. Surgery is the last thing on my mind as it costs too much.
    By the way, i’m a body builder and can’t keep up with my daily regimen as of now. Hoping you can post more topics here like this one.

  2. One injury common to runners is Achilles tendonitis/ pain, calf tightness and shin splints. Many times runners will come in with an injury on one side and not the other, which begs the question of why not the other ankle? Many times the answers to this question can be found by movement analysis or video gait analysis. One focuses on the strength and movement of the respective joint of the lower body and the other at how the body moves in during the sport.

  3. My friend got several cortisone shots for his tendonitis- he was of the 50% lucky ones that the shots worked. but he couldn’t run for a month.

  4. For several years I experience lower back pain, and after sitting for any length I had trouble straightening up and I was in pain. I also had a severe sore spot in the buttocks area. After xrays my doctor diagnosed it as arthritis in the lower spine and prescribed physical therapy. After a month or so of exercise & therapy the pain in the buttocks had gotten worse. I went back to the doctor who diagnosed it as tendonitis and gave me shot of cortisone in my butt. Lo and behold the pain disappeared and I now can get up out of a sitting position without being bent over and in pain. So it appears that my problem all along was tendonitis, rather than arthritis of the lower spine. Will it last, or should I return to therapy as he suggested.

  5. y does the shot just hurt instead of making it feel better i have tendinitus and carpol tunnel in the hand and the dokter gave me the shot where it hurt the most and it diddnt work i just want to no y it hurt ne worse than helped my hand i am 32

  6. I have carpel tunnel that was probably brought on by my rheumatoid arthritis. On both hands my thumb, index, middle and half my ring finger (split up the middle) were almost completely numb. The only sensation from my finger tips was the feeling of wet sandpaper when I touched anything.

    Cortisone injections in both wrists brought back the feeling in my hands completely. It doesn’t last but a couple years of being able to use my hands without having a surgery I can’t afford is a lot better than the alternative.
