Hi Keri!
I wish I had seen this earlier, I just got home, sorry! There is a case of chorea and masto and I have a copy of it, if you want it. This may be what is going on with you. Masto has also been associated with epilepsy and it's also been the cause of Parkinsons as well as brain damage due to hypoxia. So, masto has been shown to be connected to neurological problems, yes!
Here is that article that I have. It's short, but sweet!!! I hope it helps!

Chorea: a new manfestation of MASTOCYTOSIS
Sir: Mastocytosis is a uncommon disease, characterised by the proliferation of mast cells in various organs of the body, which presents in a limited cutaneous or a systemic form.' The central nervous system manifestations of mastocytosis include headache, dizziness, seizures and alterations in cognitive function.23 The occurrence of chorea, to the best of our knowledge, have never before been described in mastocytosis. We recently examined a patient with mastocytosis who developed choreic movements.
A 13 year old girl was admitted to hospital for study ofpruritic skin lesions consisting of reddish-brown maculopapules. A skin biopsy was done under local anaesthetic (mepivacaine 1%). Approximately 4 hours later, she developed involuntary movements. Examination revealed choreatic movements specially involving the upper extremities and the orofaciolingual muscles, with the trunk and the lower extremities involved to a lesser degree. The hands showed choreothetoid movements. Neurological examination was otherwise normal. General physical examination was normal save for skin lesions. One day after initiation of the chorea, treatment with cyproheptadine (12 mg/d) and ketotifen (2 mg/d) was instituted. Resolution of the abnormal movements began gradually during the third day after their onset and completely returned to the premorbid state on the fifth day. One year later, the patient has remained well without further choreic episodes.
Pregnancy, birth and early development were normal. There was no history ofchorea or rheumatic fever and the patient had not been treated with chorea-inducing drugs. Family history was not significant for any neurological disease.
The following investigations were all normal; haemoglobin determination, WBC and differential counts, ESR, urea and electrolytes, creatinine, blood glucose, liver function tests, calcium and phosphate, cholesterol, triglycerides, uric acid, serum protein electrophoresis, quantitative assays for immunoglobulin levels, C3, C4, autoantibody screening, syphilis tests, coagulation system tests, thyroid function tests, caeruloplasmin, serum and urinary copper, 24 hour 5-hidroxylindolacetic acid and urinary histamine levels, skull and chest radiographs, cerebrospinal fluid, electroencephalography, auditory and visual evoked potential and CT and MRI of the brain. The skin biopsy specimen showed mast cell infiltration of the dermis.
The most remarkable finding in our case is the presence of chorea that, to our knowledge, has never before been described in mastocytosis. Choreic movements were considered to be caused by mastocytosis, not just because no evidence of other aetiology was found,' but also in view that the administration of a well-known activator ofa mast cell secretion as topical anaesthetic3 provoked the choreic movements.
The role of the mast cell in production of disease appears to be twofold. As a consequence ofa high tissue mast cell concentration, there are both local effects of mast cell infiltration, as it interfers with organ function, and systemic effects resulting from release of mast cell mediators such as histamine, heparin, prostaglandins and other peptides.5 6
Chorea can be the result of structural or functional striatum damage.' In our case, the possible explanation of these movements is that as an effect of a sudden and greatly elevated level of released mast cell mediators, mastocytosis may induce biochemical alteration in the basal ganglia. This hypothesis is supported by the fact that the development of chorea was provoked by the administration of a well-known activator of mast cell secretion (mepivacaine 1%). We cannot exclude the possibility that mast cell infiltration of the basal ganglia were responsible for chorea. However, we consider this possibility to be far less likely in view of the transient nature of the chorea and that no structural lesion could be demonstrated by the neuroradiological studies. In addition, the systemic mast cell disease has been reported to involve directly virtually all organs except the central nervous system.'
Although no conclusion can be drawn from our report, we believe that the causation of the chorea in mastocytosis must be sought at a biochemical level rather than in a structural lesion.
