Because TMS is a localized treatment, there are no systemic side effects such as nausea, vomiting, GI upset, etc. The side effects of deep TMS are mostly limited to local discomfort and headaches. During your treatment, we are able to adjust the intensity so that these side effects are tolerable throughout. Typically, over the counter medications such as Tylenol and Ibuprofen can also be helpful. Overall, TMS is very well tolerated.
