Hi, Sunshyn, welcome to the community! Hope your pain is better today. I can definitely empathize with you about having an 'invisible' disease. Pain is very real, but it can't be seen by someone else. My own disease, Myasthenia Gravis, is characterized by fatigue and weakness rather than pain, but it also is a rather 'invisible' disease as far as outward symptoms go.
Hugs,
