My symptoms over a few months

[sadbunny]

-Easy bruising
-Joint pains
-Muscle pains
-Shooting pains that comes and goes every few seconds in different parts of the body (finger, hand, stomach, toes, ankle, knees etc)
-Slightly raised bumps. There's usually only one bump in that area like my lip or stomach. It's in a shape of a line and is quite painful and itchy (no possible insect bites or the like)
-Constant cold feet
-Constant debilitating fatigue and depression (not sure if the 2 are correlated)
-Insomnia
-Headaches

Hello~The first thought that came to my mind was "Chronic Fatigue Syndrome" You seem to have most of the symptoms associated with it.

Chronic fatigue syndrome (CFS) is a complicated disorder characterized by extreme fatigue that can't be explained by any underlying medical condition. The fatigue may worsen with physical or mental activity, but doesn't improve with rest.

This condition is also known as systemic exertion intolerance disease (SEID) or myalgic encephalomyelitis (ME). Sometimes it's abbreviated as ME/CFS.


The cause of chronic fatigue syndrome is unknown, although there are many theories — ranging from viral infections to psychological stress. Some experts believe chronic fatigue syndrome might be triggered by a combination of factors.

There's no single test to confirm a diagnosis of chronic fatigue syndrome. You may need a variety of medical tests to rule out other health problems that have similar symptoms. Treatment for chronic fatigue syndrome focuses on symptom relief.

Signs and symptoms may include:
•Fatigue
•Loss of memory or concentration
•Sore throat
•Enlarged lymph nodes in your neck or armpits
•Unexplained muscle or joint pain
•Headaches
•Unrefreshing sleep
•Extreme exhaustion lasting more than 24 hours after physical or mental exercise

Causes

People who have chronic fatigue syndrome appear to be hypersensitive to even normal amounts of exercise and activity.

Why this occurs in some people and not others is still unknown. Some people may be born with a predisposition for the disorder, which is then triggered by a combination of factors. Potential triggers include:
•Viral infections. Because some people develop chronic fatigue syndrome after having a viral infection, researchers question whether some viruses might trigger the disorder. Suspicious viruses include Epstein-Barr virus, human herpes virus 6 and mouse leukemia viruses. No conclusive link has yet been found.
•Immune system problems. The immune systems of people who have chronic fatigue syndrome appear to be impaired slightly, but it's unclear if this impairment is enough to actually cause the disorder
•Hormonal imbalances. People who have chronic fatigue syndrome also sometimes experience abnormal blood levels of hormones produced in the hypothalamus, pituitary glands or adrenal glands. But the significance of these abnormalities is still unknown.

Risk factors

Factors that may increase your risk of chronic fatigue syndrome include:
•Age. Chronic fatigue syndrome can occur at any age, but it most commonly affects people in their 40s and 50s.
•Sex. Women are diagnosed with chronic fatigue syndrome much more often than men, but it may be that women are simply more likely to report their symptoms to a doctor.
•Stress. Difficulty managing stress may contribute to the development of chronic fatigue syndrome.

Complications

Possible complications of chronic fatigue syndrome include:
•Depression
•Social isolation
•Lifestyle restrictions
•Increased work absences

I highly suggest your PCP for a complete work up.

I hope you feel better soon. God bless you.

Look into Undefined Connective Tissue Disease (UCTD)
This condition is an early stage of a Connective Tissue Disease, specially at the onset of  MCTD.
Usually young people in their 20s and 30s get diagnosed with UCTD  and MCTD.
You have many of the typical symptoms.
Seek a good Rheumatologist for further investigation.

Best wishes,
