Somatic Therapy is anything that makes you more aware of your body.
Yoga is a great example, and it's free, once you learn it.

It's kinda of cognitive therapy in reverse.
With cognitive therapy, you work finding insights that make you more comfortable, physically.
With somatic therapy, you make yourself more comfortable first, than find the insights that fit the comfort.

It's very powerful if you can do it although many people can't depending on how it's done.
Successfully bringing your sensations to awareness will also activate the reasons you normally repress those sensations.
If your skills for dealing with repression (normally fear) are low then you'll just want to repress the sensations again and stop therapy.
Ask the therapist if he/she has any new tools to deal with repression once it's brought to awareness.

"Ultimately the body will rebel. Even if it can be temporarily pacified with the help of drugs, cigarettes or medicine,
it usually has the last word because it is quicker to see through self-deception than the mind." - Alice Miller, The Body Never Lies
