Brief Answer:
Myalgia caused by HIIT exercise workouts - No pain, No gain.

Detailed Answer:
Dear XXXXX,

I have examined your question rather carefully. You mention that you do HIIT, which is a new regimen of high intensity workouts, right? I congratulate you for being so fitness oriented, indeed.

I have kept in mind the "stomach flu" that you mention having occurred in between.

We have broad possibilities,

First, it's quite well known that infections can indeed lead to "myalgia" - meaning the sort of muscular pains that you experience. Particularly, in the post infective stage of recovery. This is not due to the germs, but due to your bodies defence mechanism of fever to fight the germs- that needs high energy levels to maintain. The medical term is rhabdomyolysis. - This means breakdown of muscle tissue and protein to supply energy to your immune system to fight off the germs - regardless of whether medication is taken or not.

There you have a splendid explanation for the second bout of myalgia.

As for idiopathic myalgia experienced in the limbs regularly, well, we know that the slogan for any form of exercise - body building, isometrics, aerobics and HIIT - is "no pain, no gain".

And I assure you that HIIT is indeed exercise that pushes one's body over the top. HIIT gives results. However, muscle pain is a natural outcome.

I encourage most of my patients with similar problems to slightly change their exercise techniques, yet to keep up with the goals of exercise.

Given the nature of events, I suggest that you see a local doctor to ask for a medicine that probably may not require a prescription, in most places, called as serratiopeptidase. Most of my athletic patients find that this greatly helps. I strongly would request you to avoid over the counter medicines like Advil or Tylenol for the muscle pain, though they do work, for the simple reason that you might need to take them regularly, and seriously speaking, they have side effects - for example - Tylenol is bad for your liver.

Please steer clear of NSAID pain killers too.

Muscle pain is a good sign that your HIIT workouts are indeed working to keep you in perfect fitness. I am certain that as you put in the sweat, the muscle pains will vanish and subside as your body grows stronger.

You might also want to ask your HIIT trainer as regards this line of thinking. I am certain that he or she would agree to this line of thinking.

Since, the fever has vanished, there is no reason to intervene medically, and indeed, I do see no link between tendonitis and these events.

I am certain that when your local doctor prescribes you a low dose of serratiopeptidase tablets, you'll immediately feel relief - from your main complaints - muscle pains - "myalgia"

I do encourage you to ask me any doubts or questions as regards such health issues.

It's been great knowing you,
Your sincerely,
Dr. Neel Kudchadkar
