Red bumps on knuckles....Any ideas what it is? Please help

Ever since I was about 16, I’m 21 now, I have had these weird red bumps that would appear on my fingers. I would sometimes go months without getting them and other times I would have a “flare up” almost every week. This past year I have been getting them more often and recently I have noticed that the bumps are appearing not just on my fingers but on my toes too and they are localized around my knuckles.  The weird thing is they are not really that noticeable unless you’re looking directly at them. Sometimes they are itchy but mostly they are kind of sore to the touch but I can’t tell if it’s just the skin or my actual knuckle that is kind of sore. My hands and feet are normally on the colder side but when they are warm (like after showering) my knuckles turn a deep purple/blue color. I never really thought it was a big deal but I did bring it up during a routine physical a couple months ago and my doc thought it was just eczema (unfortunately I didn’t have it at the time to show her) but after doing research I am almost positive it isn’t eczema but I’m totally lost on what else it could be. Does anybody have any ideas? I think it might be some sort of autoimmune diseases since I have other symptoms such as (fatigue, lack of energy, hair thinning, anxiety, and heart palpitations) but after multiple blood tests and a full heart work up my doctor can’t find anything wrong with me. Any info or advice would be greatly appreciated.

You need to have a complete thyroid panel to rule out hypothyroidism (type 1 and 2 as well as Hashimoto's and hyperthyroidism).
Fatigue, lack of energy &hair thinning are hallmark signs of hypothyroidism , while anxiety and heart palpitations are signs of hyperthyroidism.
Unfortunately, there are periods, where for a while a patient can experience intermittently both hypo and hyper states.

TSH, Free T3, Free T4, Reverse T3, Anti-TPO, Anti-Tg , TSI are the thyroid tests to have done.

It seems that you may also have circulation issues which
have caused Reynaud's.
Your skin allergy- like symptoms could be a reaction due to your body's inability to regulate temperature.

You should also rule out iron deficiency, anemia, B12 methylocobalamin (MMA test- repeat within a few weeks), Vitamin D, tissue  magnesium (your doctor won't order this one-you need an alternative practitioner*), iodine, selenium, zinc.

*In lieu of testing, you can opt for a trial of transdermal magnesium oil treatments, which is actually 1/2 water, 1/2 magnesiium chloride flakes dilution, sprayed allover the  body (except sensitive areas) left on for 20-30 minutes to absorb and then rinsed off really well!
Every other day for a few months should do it.
It usually helps in many different ways, as magnesium is involved in numerous processes.
Anxiety depletes tissue magnesium fast!
And this is one of the safest and most efficient ways to supplement.
Oral magnesium is very laxative and notoriously inefficient.

Best wishes,
Niko
