Two possibilities to mention:
1. If your skin is tender to touch and burning is not affected by body movements and different positions, then it can be shingles (Herpes zoster virus reactivation in one of the spinal nerves). Nausea can be also from shingles. This causes burning pain going like a stripe from the spine to the front. Often (but not always) rash appears after some time. Neurologist would tell you, if there is any available painkiler for your situation.
2. Bulging or herniated disc or some other disorder in your thoracic spine (osteoporosis, arthritis..) could cause pinched spinal nerve. This type of pain would be affected by different body positions and would not be tender to the slight touch. Again, neurologist could say more.
There is considerable controversy over the earliest age at which it is clinically, morally, and legally safe to use GnRH analogues, and for how long. The sixth edition of the World Professional Association for Transgender Health 's Standards of Care permit it from Tanner stage 2 but do not allow the addition of hormones until age 16, which could be five or more years later. Sex steroids have important functions in addition to their role in puberty, and some skeletal changes (such as increased height) that may be considered masculine are not hindered by GnRH analogues.
And, exacerbating these two age-related erosive events, some catabolites
of tryptophan can lead to the formation of mutagenic nitrosamines or
the activation of an immunosuppressive receptor (which is usually
triggered by toxicants such as xenobiotics), promoting carcinogenesis
(Mezrich, et al., 2010; Chung & Gadupudi, 2011).
The consumption of a supplement of tryptophan will likely nurture or augment these disastrous age-associated disease states, by raising injurious tryptophan derivatives (particularly in the presence of a vitamin B6 deficiency, an insufficiency of stomach acid, a magnesium deficit, and a vitamin B3 deficiency).
Furthermore, tryptophan side effects in regards to greater mortality were shown in animal experiments (., Catrina, et al., 2001) using melatonin, whereas the study authors cautioned:
“[...] melatonin had a deleterious effect on the survival rate raising the question whether it is correct to assume that the hormone shows lack of adverse reactions.” [emphasis added]
In regard to serotonin's involvement in the promotion of higher mortality, one of its anti-longevity effects is conceivably the reabsorption of phosphate (a pro-inflammatory chemical) by the kidneys since klotho, an anti-aging protein, facilitates the excretion of phosphate from the kidneys (Peat, Nov. 2012).
Since tryptophan, serotonin, and melatonin meddle with basic energy production in cells, and since metabolic efficiency and functionality decreases proportionally with aging (Fannin, et al., 1999; O'Toole, et al., 2010) due to various factors, it seems coherent in biological terms that these substances are less prevalent, thus less “essential” or needed, in older people, as a further decrease of an already suboptimal general metabolic working order will aggravate physiological function systematically, increase the risk for disease (as exemplified and foreshadowed with tryptophan side effects), promote the aging process, and explains the increased mortality related to the administration of these substances.
Several tryptophan side effects, such as tryptophan's carcinogenic activities, the deterioration of metabolic energy function, and the promotion of hypertension, can rather readily account for a greater death rate.
