As per the title, I'm wondering what kind of physical symptoms have you experienced due to your anxiety?

I'm prompted to ask because I have been having some health issues which includes several symptoms that seem like they could point towards autoimmune diseases (particularly Sjogren's and IgG4-RD).

I started experiencing symptoms back in 2018 and was in a state of absolute misery for over a year and a half. The list of symptoms is LONG and I have multiple posts describing them to anyone interested. But in short it affected my entire digestive system, my eyes, my skin, my musculoskeletal system and/or nervous system etc. 

The thing is, I seen multiple doctors and had multiple tests and nothing really conclusive ever pointed to a cause. I have been dealing with a delightful cocktail of anxiety disorder and depression for pretty much my entire life; anxiety starting as a child and depression in my teen years. I never took medication or had therapy, I always pushed through and coped in my own ways. This ultimately lead to my family doctor chalking up my symptoms as being caused by mental illness, namely untreated anxiety. I'm not excluding this possibility, but the anxiety that the symptoms caused me started quickly manifesting in health anxiety and OCD, and it's so hard to make a separation of what is what.

I never had these kind of symptoms in the previous 10+ years of anxiety, even at my worst lows with prolonged panic and stress. These symptoms started to show up and progress over a period of 3-4 months and then compounded and worsened, and with them so did my anxiety and depression. Eventually it all started to dissipate going into 2020, and for nearly a year the physical symptoms were pretty much all gone. During this period I still had hard periods of mental health, worrying about covid and the like, but the physical symptoms stayed absent. Recently, just over a month ago, I started noticing these symptoms slowly creeping back. I wasn't notably anxious or stressed leading into this onset. Not long after this started returning I started getting anxious again worrying that the hell I endured before would be something I have to deal with for my entire life. Then on top of that, my girlfriend of 5 years broke up with me. 

I spiraled, quickly. I was in a state of turmoil and panic having to worry about my health and coping with the emotional stress of a breakup. I was and am not okay.

I returned to my doctor, and she was quick to dismiss my concerns of a disease flare-up and focused on my anxiety. I totally understand this approach, since our previous investigation yielded no sign of disease and it is good to attempt elimination of anxiety and the havoc it creates on my body. She prescribed me Lexapro which I am still waiting to take because I'm lined up to speak with a counselor who I want to help me on the journey that is treating this illness. I am worried about it making things worse because I'm not sure I can handle added stress right now, so I dared not take it without counsel. And even still, while I understand the importance of this approach, I just can't shake the feeling that there is something else going on that doctors just haven't been able to detect. I feel like I'm going crazy because the logical part of me tries to rationalize that this feeling is manifestation of my health anxiety; however, I'm in tune with my body and my instinct just keeps telling me it isn't just anxiety and to seek medical attention. But every time I speak to a doctor since these symptoms return I just get dismissed because of my anxiety. I feel so overwhelmed.

Anyways, here I am ranting on reddit again, digressing from the main point of the post. I guess I'm doing this as an attempt to gain peace of mind that maybe I'm not the only one.

I'd be interested to hear any of your experiences and perhaps how you cope with things.
