Botox Injection in Neck for Fibromyalgia: Now Have Extreme Side Effects

what you are experiencing is the law of unintended consequences. this happens all the time with botox injections, sometimes with actually good results, sometimes with poor results. the platysma muscle in the front of the neck is a depressor (it lowers the jaw) as opposed to the muscles in the back of the neck which are elevators of the head (allow you to look up). when the posterior neck muscles were injected the balance bewtween depressor and elevator was upset leading to other muscles  trying to do jobs they are not well positioned to do, leading to all sorts of muscular mayhem.  part of me wants to try to balance the muscle function with further injections, luckily the smarter part of me will prevail and recommend you ride it out and consider wearing a soft collar to help relax the muscles that are overworking. good luck

Botulinum toxin (BTX)  or Botox injection is being increasingly used 'off label' in the management of chronic pain. Data support the hypothesis of a direct analgesic effect of BTX, different to that exerted on muscle. Although the pain-reducing effect of BTX is mainly due to its ability to block acetylcholine release at the synapse, other effects on the nervous system are also thought to be involved. BTX affects cholinergic transmission in both the somatic and the autonomic nervous systems. Proposed mechanisms of action of BTX for pain relief of trigger points, muscular spasms, fibromyalgia and myofascial pain include direct action on muscle and indirect effects via action at the neuromuscular junction. Invitro and invivo data have shown that BTX has specific antinociceptive activity relating to its effects on inflammation, axonal transport, ganglion inhibition, and spinal and suprasegmental level inhibition.
The mechanisms of action, efficacy, administration techniques and therapeutic dosage of BTX for the management of chronic pain in a variety of conditions shows that although muscular tone and movement disorders remain the most important therapeutic applications for BTX, research suggests that BTX can also provide benefits related to effects on cholinergic control of the vascular system, autonomic function, and cholinergic control of nociceptive and antinociceptive systems. Furthermore, it appears that BTX may influence the peripheral and central nervous systems. The therapeutic potential of BTX depends mainly on the ability to deliver the toxin to the target structures, cholinergic or otherwise. Evidence suggests that BTX can be administered at standard dosages in pain disorders, where the objective is alteration of muscle tone. For conditions requiring an analgesic effect, the optimal therapeutic dosage of BTX remains to be defined.  I first introduced the use Botox® for pain around 2000. The use of Botox ®(Botulinum toxin type A) treatment for fibromyalgia reduces both pain and muscle spasm. If a patient has frequent spasms and pain, then Botox® is a superb treatment
Botox works by effectively relaxing muscles as well as decreasing the messages transmitted through pain receptors. Which means that the sensation of pain is greatly reduced. . After injection the pain relief usually occurs within 7 days. The levels of pain relief experienced by patients varies, according to the severity of their condition etc., but it is usual for patients to feel significant levels of pain reduction for up to 4 months. So although it is not a permanent means of controlling pain, it is effective as a long-term way of pain
Management and by seeing patients every 4-6 months the can essentially remain pain free. The procedure is very safe due to the fact that one should use onlysmall doses of Botox® . There are significant risks associated with Botox but only in unskilled hands usually in large doses in Children. In some cases, where there is an underlying medical condition other than fibromyalgia such as Myasthenia Gravis where Botox cannot be used. Botox is quite amazing when dealing with pain and muscle spasms that you may have. It cannot deal with any other symptoms. However the pain relief can really enhance your life!  Arnold Klein
