Help me to be pain-free while playing piano!

Hi. I'm Mike! I am a Piano teacher and i love to teach and perform, but ive been having pain in my hand and i need your help for the medical treatment.

I have been suffering from worsening chronic pain for 8 years on my right arm. It has impacted my life very negatively and has depressed my emotional state. I have leaped from doctor to doctor, MRI to EEG, EMG, Xray and none were able to help.

BUT! recently I've had the pleasure of seeing a neuroscientist and an osteopath at the AIMIS Clinic who have diagnosed me with complex regional pain syndrome ( CRPS ) and Tension Myositis syndrome ( TMS ). With recent technological advances, these doctors believe that my symptoms can be greatly improved with these two devices:

Transcranial Direct-Current Stimulation (tDCS) & Transcutaneous auricular vagus nerve stimulation (taVNS)
the treatment involves 3 weeks of taVNS and 10 sessions of tDCS
its going to cost me approximately 1950 euros
A friend has already helped me with 400 so there is 1450 remaining

Rent is very expensive and I don't think that by myself i would manage to afford this. However, I don't want to delay my healing process any longer.

If anyone could help me achieve my dreams i would greatly appreciate it and it would mean the world to me to finally be pain-free! <3

Sincerely yours,
Mike <3
