Can an acoustic neuroma be aggravated by sauna use?

@philomenamarybarry111 Welcome to Connect. You are asking an important question, however, Connect is not staffed my medical experts. This is a patient forum, so no one here can offer medical advice. The best person to answer your question would be a medical expert such as a neurologist or neuro surgeon who understand tumors of the nervous system.

There are also different kinds of saunas, dry heat, steam, and infra-red, so that would be something to add to your question. All saunas would increase your heart rate and can cause dehydration through sweating.

There are other discussions on Connect where patients are talking about infra-red saunas and neuropathy. These may be of interest.

If you do get an answer to your specific situation, would you come back and share it here?

@philomenamarybarry111, I add my welcome. How long have you been living with an acoustic neuroma? How is your hearing and balance?
