Your symptoms suggest a possible combination of lupus and thyroid disorder, maybe Hashimoto's, an autoimmune thyroid disease that causes enlarged thyroid and symptoms of hypothyroidism, sometimes hyper early on. The joint pains and rash are suggestive of lupus or similar autoimmune disorder. Memory problems can occur with lupus and hypothyroidism. I would suggest seeing a Dr to get some basic labs done to rule these out, then follow up with specialists as needed.

I had 20+ years of what my local doctors thought was IBS. My doctors tested me repeatedly (ugh) for inflammatory bowel conditions (IBD's) like Crohn's, Ulcerative Colitis, etc. Also, for Celiac sprue. I mention those GI conditions because, interestingly, certain skin rashes can occur in them.
In addition to those flat-out GI conditions, I too found myself thinking of lupus, its "close cousins", and thryoid. And of course there could be more possibilities (we're only patients here).
Your skin rash, if properly identified, could offer clues, but I agree that starting with a GP makes more sense. Starting with ONLY your rash could be too narrow an approach. You want a "wide net" cast.
In addition to my 20+ years of GI misery, over time more problems appeared: migraines, skin rashes, pain, fatigue, brain fog, urinary misery, etc. I was eventually diagnosed with lupus. (But my rash was first biopsied & subjected to immunofluorescent stain tests before being diagnosed as lupus-specific.) Yet similar symptoms can pan out very differently in different patients; and a single underlying condition might be found (I have a single dx), or multiples (many people have multiple dx'es). So those are just more reasons to work from the ground up.
Post anytime with more questions, updates, or just to touch base. We'll look forward to hearing more. Please keep trying, and good luck. Bye for now, with warm wishess, Vee
