Given the limitation on natural movement you described in your original post, is continuing to practice even practical under the circumstances? It would seem that there's no benefit to be gained, and instead you risk aggravating the problem.
If you suffered a serious, immobilizing illness or injury (e.g., a fracture, a severe burn, etc.), you would have no choice but to stop practicing while you convalesce. Your present condition may seem trivial in comparison, but it could potentially be equally serious. I urge you to seek professional care as soon as possible, as any other course of action bears at least some risk of permanent damage.
