It would be hard to give you much constructive advice without any additional info. Knowledge of your age, presence of any other conditions, as well as info on whether the presence of chicken pox is based on medical diagnosis or is just a suspicion would help. This is because, firstly chickenpox in children and adults can be quite different, with adult chickenpox being a lot more serious; secondly, German measles is a similar viral infection that is known to cause pain in the joints, often in the region of the neck and surrounding areas. Assuming that you do have chickenpox however, I would strongly urge you to consult your health care provider and report these developments.
Joint pain, particularly head and neck pain as described by you, are often indicative of complications. Persistent abdominal pain and fevers are also not uncommon under such circumstances. At the same time although you need to be cautious there is no need to panic as head aches, neck and face pain are also not uncommon in a straightforward case, free of complications. Some information on the typical symptoms should help to clarify your doubts and enable you to better judge the situation.
The typical symptoms of chickenpox would include a mild fever and even headaches, followed by the characteristic itchy rash a few days later. The rash turns into blisters and these generally afflict the trunk of the body but are not restricted to it. They can also appear on the arms, legs, and face. The disease is also at times accompanied by a severe cough. Feelings of fatigue, exhaustion, tiredness and dehydration are common. For this reason diet and liquid intake are important considerations when treating chickenpox.
In children infected with the chickenpox virus, there are usually no complications, but this is not the case with adults. In case of complications, symptoms include bacterial infection of lesions, difficulty swallowing and breathing because of throat lesions, pneumonia or encephalitis, and persistent fever pains in the joint, particularly head and neck aches.
As mentioned earlier although the neck and head aches are symptomatic of complications this is not necessary, and hopefully not the case for you. Owing to the fatigue, exhaustion, and dehydration associated with chickenpox it is also possible to experience muscle aches and joint aches that may even be painful, if you do not get adequate rest. In addition make sure you follow a diet recommended for chickenpox patients and maintain an adequate fluid intake.
