Trigger point injections use pharmacologic agents such as lidocaine, corticosteroids (e.g., methylprednisolone, triamcinolone acetonide), hyaluronidase (Amphadase), onabotulinumtoxinA, sodium bicarbonate, and ozone, as well as normal saline or sterile water.20 No single pharmacologic agent or mixture of active drugs has been proven superior to another in the treatment of trigger points, nor has any agent been proven superior to placebo.2,21 PT has also been studied as a tool for trigger point management.9,12 A recent meta-analysis of 24 RCTs using PT to manage trigger points showed beneficial effects.16 These PT programs improved pain-pressure thresholds, reduced pain intensity, and improved range of motion, but they showed no effect on improving disability in patients with trigger points. Myofascial trigger points are hypersensitive nodules that can occur in tight bands of skeletal muscle and may cause motor, sensory, and autonomic pain symptoms; decreased range of motion; and musculoskeletal disability.1–3
Family doctors are particularly uninformed about the causes of musculoskeletal aches and pains33 — it simply isn’t on their radar. Family doctors aren’t really equipped for troubleshooting chronic pain.Comic by Loren Fishman, HumoresqueCartoons.com What’s useful in the theory of trigger points? Many trigger points feel like something else. Trigger points complicate injuries and other painful problems. What makes trigger points clinically important — and fascinating — is their triple threat.
And the topic is just trickier than it seems to be, so it’s not really surprising that doctors aren’t exactly muscle pain treatment Jedi. Aches and pains are an extremely common medical complaint,18 and trigger points seem to be a factor in many of them.1920 They are involved in headaches (including migraines),2122 neck pain and low back pain, and (much) more. Garvey, T. A., Marks, M. R., and Wiesel, S. W. A prospective, randomized, double-blind evaluation of trigger-point injection therapy for low-back pain. POME can occur during or after any injection throughout the course of therapy and includes symptoms such as the urge to cough, shortness of breath, throat tightening, chest pain, dizziness, and syncope (46). Overall, levels were similar after the third and fourth injections, with a mean Cmax of 813 ng/dL reached by day seven and a mean Cmin between 323 to 339 ng/dL by week 10 after each injection. Other common adverse effects with TC use are local inflammation and pain at the site of injection, also due to IM administration (41).
One trigger point therapy treatment completely relieved a nasty stubborn hip pain that I'd had for five months! But most symptoms caused by myofascial pain syndrome are simply the familiar aches and pains of humanity — millions of sore backs, shoulders and necks. Another client once spent three days in hospital for severe abdominal pain that doctors couldn’t diagnose — her pain was mostly relieved by massaging a trigger point in her psoas major muscle.52 Massage therapists have a lot of hands-on experience of muscle tissue, but know surprisingly little about myofascial pain syndrome.
The decision to undergo a trigger point injection should be made in consultation with your healthcare provider. The effects of a corticosteroid injection may take a few days to a few weeks to be fully realized, and the duration of the effects can vary depending on the individual case. In general, some patients may experience immediate relief of their pain and discomfort, while others may take several days or weeks to notice a difference. However, patients may experience some mild discomfort or soreness at the injection site for a few days after the procedure, and they may be advised to avoid strenuous activity during this time.
This condition is very common — up to 15% of females of reproductive age have it. Excess testosterone in male children can lead to precocious (early) puberty, which is when puberty begins before the age of nine. Excess testosterone affects your body differently depending on your sex and age. The two charts below list the general normal ranges of testosterone based on age and sex.
On day one, serum testosterone was within physiological range in both gel groups, reaching a Cmax of 560±31 ng/dL in the 50 mg/day group after 22 hours of application and 745±40 ng/dL in the 100 mg/day group after 16 hours. A multi-center, prospective randomized trial compared the PKs, efficacy, and safety of the transdermal system to IM testosterone enanthate (TE) injections (25). Each pump delivers 5.5 mg of testosterone, with the recommended dose of two pumps (one actuation per nostril) three times a day, for a total daily dose of 33 mg. It is recommended to check a testosterone level between 4 to 12 weeks after therapy initiation prior to the morning dose (14). The preparation mimics physiological circadian testosterone rhythm, with serum levels quickly increasing after insertion and peak levels obtained by the second dose with no accumulation over time (15). When the product is discontinued, testosterone levels drop below normal within two to 4 hours, allowing for quick reversal if necessary. Oral formulations of testosterone are not approved in the USA, due to historically being linked with liver toxicity and fluctuations in testosterone levels (8,9).
Two weeks after initiation of therapy, a serum testosterone level should be measured (early morning after patch application the night prior) and patch dosing adjusted as necessary. The recommended starting dose is one 4 mg/day patch (not 2×2 mg/day patches) every 24 hours applied nightly. There are also concerns regarding pellet removal for patients experiencing androgen related side effects. Serum levels peaked at approximately one month and were sustained in the normal range for four to five months with either 600 mg dose and for 6 months with the 1,200 mg dose. Each regimen was separated by at least 6 months, and the next one was not initiated until testosterone decreased to hypogonadal levels. Subdermal testosterone pellets were the first effective formulation for androgen replacement therapy, developed in the 1940s (20). Testosterone nasal gel is another non-invasive alternative with simple administration, low total daily dose, and no concern for secondary transfer.
