Introduction/BackgroundI had been practising acupuncture for 30 years and noticed while working in the rheumatology clinic that costochondritis had a particular response to acupuncture. As this condition is extremely debilitating and often misdiagnosed, a case series of 8 cases is presented, the majority of whom were seen in primary care.Description/MethodCostochondritis is characterised by anterior chest pain associated with painful tender costochondral (CC) joints felt on palpation. These mainly affect the 2nd to 5th costochondral junctions, either unilateral or bilateral. Other areas of the anterior and lateral chest wall can also be affected. The pain is often severe and nocturnal, of sudden onset and can be associated with shock, nausea and dyspnoea, causing patients to call for an ambulance. Tietze's syndrome is a rare variant of this, usually affecting younger patients.Patients with persistent chest wall pain were offered acupuncture. Details of age, duration of symptoms, number of treatments and VAS pain scores were recorded day and night, (Table 1) pre and post treatment Patients with thoracic pain were excluded.0.25*25mm and 0.25*30mm needles were used with silicon tips and a guide tube, to help prevent painful insertion. An infra-red lamp (Bio-lamp) was used + electro-acupuncture (EA) if insufficient improvement after two close treatments, sessions were continued weekly.Acupuncture points used were local tender/trigger points + distal Chinese points P6 and LI4. Other points used were CV 17, GB 34, SI6, GB39 or Sp 6 and St36. An average of 4.7 sessions were needed.Audit of Acupuncture Treatment Table 1P15 Table 1PATIENTAGEDURATION OFNUMBER OFVAS INITIAL (0-10)VAS FINALYEARSPROBLEMTREATMENTSDAYNIGHTDAYNIGHT1375 MTHS410100022618 MTHS8 (1 EA)5.57.5023653 WEEKS5 (+EA)79114584 DAYS4972256210 WEEKS7 (+EA)68026346 WEEKS447227289 MTHS314008255 YEARS38700Recurrence of pain3651 WEEK4 (+EA)88126345 WEEKS228227282 WEEKS11311Six patients took daily analgesia which was rapidly reduced to nil. All completed their treatment until their pain stabilised. There were no adverse events.Average improvement in the day was 89% and night 85%. Recurrences of pain improved by 11% in the day and 72% at night. The attacks of severe chest pain and dyspnoea stopped, abating anxiety.Discussion/ResultsCostochondritis is a highly debilitating condition and I had noticed that acupuncture could be a dramatic treatment for this[i]. It can affect up to a third of patients attending emergency departments with atypical chest pain[ii] and 1-3% of patients in primary care[iii].It seems to be a missed diagnosis by Accident and Emergency (A&E) doctors and GPs, perhaps because the chest wall was not carefully palpated. One patient had ankylosing spondylitis (AS) and another had systemic lupus erythematosus but attributed her pain to prolonged laughter. Five patients attended cardiology clinics including one who had a coronary angiogram. Another had tests for upper abdominal pain which also were normal.All the patients were female although quoted F:M ratio is 7:3Differential diagnoses include: acute coronary syndromes, lung problems, trauma, upper gastroenterology pathology or neoplasiaPathogenesis is unclear but the onset can be acute and follow:Respiratory tract infection Extreme sneezing, coughing or laughterChest wall trauma Micro trauma from costovertebral dysfunctionFibromyalgia Inflammation from inflammatory joint disease.[i] Alexander R; White A.

Prim Care (Review) Dec 2013 40(4): 863-87Key learning points/ConclusionNormal management of costochondritis includes analgesia, physiotherapy, steroid injections and occasionally surgery[i]. 30% can have protracted pain. There are isolated reports of acupuncture for this condition, integrated with conventional medicine[ii] [iii]. Acupuncture also has been used for myofascial trigger points including costochondritis[iv].Acupuncture is now an accepted modality of pain management and in 2021 was recommended in NICE guidelines for the treatment of Chronic Primary Pain alongside exercise programmes and CBT ahead of analgesic medication[v]. It has also been recommended in the management of low back pain in patients aged 60 years and over as a non-drug treatment[vi].This paper highlights the fact that acupuncture appears to be a safe effective treatment for costochondritis, with further research and more access needed for this therapeutic modality.Increased awareness of this condition would make complex invasive investigations less necessary.[i] Gologorsky R; Hornik B; Velotta J.
