Yes the horrible painful knots inside our elbows is not tennis elbow or anything that can be drained. It's a fibromyalgia tender spot knot of muscle. I will practically pass out if anybody tried squeezing them. I rub mine with arnica cream and CBD/THC salve for a little relief.
I too have painful reactions for several days after a regular massage or acupuncture and have found that I need to request a gentle soothing massage and minimal acupuncture treatments in general because fibromyalgia makes us so sensitive and reactive.
I have a wonderful physical therapist who works with me.
I also LOVE Cranial sacral adjustments which are very gentle and don't make you feel like you've been in a car crash the next day. They are very subtle but helps realign our bodies from the continual twisting and contorting of our muscles which pull and torque our ribs, spine and bones causing spasms and pinched nerves.
I'm definitely the worst at night causing sleepless insomnia so I'm forced to take medication to get as much sleep as possible to maintain my health.
My latest most effective combo is an old fashion sleep aid called Hydroxizine and Baclofen which is a muscle relaxant to stop my muscles from twisting and spasming. Taking both of they allows me to sleep. It's given me huge relief. It took a long time to come up with this. Everybody is unique and what works for one might not work for another. We do all share allot of lousy symptoms, that's for sure. I just hope we all can get some relief.

I agree with you Karen! I'm fed up with this abusive attitude we are getting from sometimes the same doctors who previously prescribed the meds to us. I've been through this entire year struggling to find a doctor that will accept me as their patient knowing that I have chronic conditions that are not curable. Bottom line is that they refuse to prescribe the pain medications that we need to remain a functioning person.
After being rejected over and over, I have finally gone back to one of my Pain specialists who understands my conditions and is will ing to write my prescriptions according to the approved guidelines. I will now just find a new primary doctor who is an Internist who can understand my complex medical conditions and I won't need to rely on that doctor for my medications.
I've finally come to the realization that I actually know far more about fibromyalgia than most any doctors so I'm no longer going to waste my time searching for one.

I have a lump (it feels like a muscle mass) on the inside of my right elbow as well. In addition I have them on the inside of my wrists, some on my fingers and on one knee. They are painful to the touch. My pain mgmt doc said they are common for people with severe fibromyalgia. I’m glad to know that at least I am not the only one but sad that you are suffering from them as well.

I had same diagnosed as tennis elbow i still have pain of and on did nerve testing results were in normal range been over a year now

I would highly suggest not to ever get any injections near yr spine it causes Arachniatitis AA!! Its one of the most painful & worse conditions known to man!!! Please dont get any some moms r getting it from only one epidural when having their baby!!! Its so sad! Injections are not FDA approved if yr dr pushes you to get them tell them that in your response!!! Its ok to get them just NOT near yr spine!!!
