Your body secretes inflammatory molecules called cytokines in response to assault. Viral/bacterial infection, mechanical, vaccines, autoimmune etc.

These may flare and abate during the day. Also during the day your own cortisol levels fluctuate as well. Highest in the morning after breakfast, lowest at 4am or so. Second high around 8pm and minor low at 4pm. Cortisol response can abate inflammatory situations, and if your cycle of pain matches this cycle one can think you have an inflammatory issue.

If you flare and abate, you may be allergic to something depending on your exposure. Trying some antihistamines like Benadryl may reveal this. I flare from potatoes! It takes hours to manifest, usually at night. Took years to discover this.

If you are gluten intolerant there may be cycles too depending on what you eat. MSG a very common food additive is notorious as a dietary trigger.

Flaring can be from blood sugar aberrations. Lows may flare burning pain, and the symptom may resolve when more normal.

Sensory nerve endings are fragile...they can be damaged. Nerves and their insulated axons can be damaged, on the way to the spine. Also the brain may become accommodated to pain, and register it even when the limb is GONE (amputated). This is called phantom pain.

So your question is complicated. And there are different answers for each person.

The best way to use this forum is to read the Subforum above first. Don't do so much at one time. Cruising the net can become confusing, esp if you don't have a medical background or training to know what is valuable, what is old news, and what is applicable information.

Some people have stated here that as healing progresses, there are good days and bad. This is because the nerves, may fire some days more than others. Severe changes in barometric pressure, as LOWs, which move in, typically cause more pain.

Maybe keeping a journal of your food and daily activity will reveal something for you. A journal can be very helpful for doctors too.

There is new evidence that some people carry a defective gene in the ganglia along the spine that result in the nerves there being unable to repair themselves. The new studies have just reported this, and suggest that SOMEDAY stem cell treatment may help. But for those with the gene error, we have no diagnostic test yet.

So just start reading.
