Attain brain-tumour in left sylvian-fissure that previously ruptured. was debulked but will return and need future surgery. globules in ventricles from rupture. lifting weights there is bad pain in back of head, nowhere near tumour why could this be?

Please contact your neurosurgeon for further advice.

Not feasible to properly address your confusing question, as need to understand size of tumor, presence of mass effect, and what is meant by rupture. (Was this a highly vascular tumor, or a glioblastoma?). Personally, just based on vague description, would avoid weight lifting totally. Pain may be consistent with increased intracranial pressure. Neurosurgeon should be closely involved.
