I am also figuring this out.  So how about emailing me at swalesdiana@gmail.com and lets figure this out together

In 70-year-olds, DHEA (Dehydroepiandrosterone) levels are significantly lower than in young adults, typically around 20% of youthful levels, according to the National Institutes of Health (NIH) | (.gov). This decline is a natural part of aging, with DHEA production decreasing from its peak in the third decade of life. While some studies suggest potential benefits of DHEA replacement in older adults, particularly in women, results are not consistently positive across all studies. 

Welcome @bold-95.   That's a tough situation.   Understanding DHEA Deficiency in Menopausal Women A major cause of hypothyroid is iodine deficiency.  In the 60's bread had 90 mcg, milk 100 mcg per cup and we used iodized table salt.  A sandwich and glass of milk supplied 300 mcg,  Now in the US bread does not use iodine as dough condition, milk has a bad name and table salt is avoided.  Net reduction from 1970 to 1984 of 50% of iodine intake.   Urinary iodine levels (mg/dL) in the United States, 6-74 years of age NHANES I, 1971-74 Median 32.00 2NHANES III, 1988-91 Median 14.5 NHANES 2000 Median 16.1 There has been a trend for increased prescribing of levothyroxine (LT4) in the United States.  LT4 was the tenth and seventh most commonly prescribed drug based on the number of prescriptions in 2005 and 2006, respectively. From 2008 to 2011 the number of LT4 prescriptions rose from 99 million to 105 million, with LT4 being the second most prescribed medication.1 From 2012 to 2016 the number of annual LT4 prescriptions increased steadily from 112 million to 123 million, with LT4 being the most prescribed medication.2,3 During 2017 and 2018 LT4 was the third most prescribed medication, with 98 million Levothyroxine prescriptions trends may indicate a downtrend in prescribing. DHEA and hypothyroidism are linked, with some evidence suggesting that low DHEA levels may be associated with hypothyroidism.

For minor aches and pains, my go to is Original Alka-Seltzer.  Aspirin and bicarbonate.  It is dissoved in water before you swallow it so no tablets to aggravate the stomach wall.  The bicarbonate buffers the stomach acid for upset stomach. Willow bark contains a chemical called salicin, which is similar to aspirin. It has pain and fever reducing effects in the body. The last time I took Advil for serious pain it spiked my BP to 190. Some blood pressure medications have been linked to rib pain or musculoskeletal pain as a side effect.  I had to stop Atnenolol because it had me bent over like a 90 year old with a walker.  Another med prescribe by my doctor left my knees unstable.  Currently, Losartan has weakened my back and thighs.  Can't walk to my mailbox at the street and back without having to rest my legs.  Upper body is however increasing muscle mass.  No one believes me though; think I'm malingering.  Those blood pressure meds also had no effect on my BP, but doctor wants me to continue on (man up, its good for you, with the Losartan + clonidine.  What has been working is Clonidine.  It has lowered my BP. but it is considered third tier BP med.  No side effects and it lowers my BP from 160+ to between 115 and 139.  

@bold-95, welcome to the forum. Rib pain can be caused by Chondritis, an inflammation of the cartilage in the ribcage or breastbone.  Vitamin D deficiency causes this condition and Osteopenia. Celiac disease damages the lining of the small intestine, making absorption of nutrients like vitamins difficult.  Nutritional deficiencies result.  Diseases can be caused by not having enough of certain vitamins and minerals. Vitamins are chemical compounds that our bodies cannot make, so we must get them from food or supplements.  Vitamins are crucial to our bodies functioning properly.  Eating a nutritionally dense diet is important, but to correct nutritional deficiencies, supplemental vitamins are needed.   Over the counter pain relievers like NSAIDs and PPIs can cause additional inflammation and damage to the small intestine.  OTC pain relievers worked for me but they hurt my digestive system worse.  Yes, Cobalamine Vitamin B12, Pyridoxine B 6, and Thiamine B 1 have an analgesic effect when taken together.   I'm leaving links below so you can see for yourself.   Analgesic and analgesia-potentiating action of B vitamins.     https://pubmed.ncbi.nlm.nih.gov/12799982/#:~:text=Disregarding pain resulting from vitamin,three are given in combination.   Mechanisms of action of vitamin B1 (thiamine), B6 (pyridoxine), and B12 (cobalamin) in pain: a narrative review https://pubmed.ncbi.nlm.nih.gov/35156556/   B Vitamins in the nervous system: Current knowledge of the biochemical modes of action and synergies of thiamine, pyridoxine, and cobalamin https://pubmed.ncbi.nlm.nih.gov/31490017/   Role of B vitamins, thiamine, pyridoxine, and cyanocobalamin in back pain and other musculoskeletal conditions: a narrative review https://pubmed.ncbi.nlm.nih.gov/33865694/   The Combination of Neurotropic Vitamins B1, B6, and B12 Enhances Neural Cell Maturation and Connectivity Superior to Single B Vitamins https://pmc.ncbi.nlm.nih.gov/articles/PMC11987730/
